A couple of years in the past, South African documentary filmmaker Craig Foster felt burnt out from years of operating on onerous nature movies. Desiring a reset, he returned to the underwater kelp forests off the southwest tip of Cape The town.
“My earliest recollections, my private and maximum tough recollections had been of this implausible coast and diving in what I name ‘my magical adolescence woodland,’ ” Foster says. “It is without doubt one of the largest ecosystems on the earth.”
Foster vowed to dive — with out a wetsuit or oxygen tank — on a daily basis for a 12 months into the cold waters close to the place he grew up. The sea used to be now and again as chilly as 46 levels, however his frame steadily tailored.
“Daily, I slowly began to get my power again and discovered that there used to be this entire new method of having a look at this underwater woodland. And I began to come back alive once more,” he says.
The waters had been teeming with sea creatures, however Foster says his encounters with one explicit octopus stood out. Over a chain of dives, the octopus started popping out of her den to seek or discover whilst Foster watched.
“That is after I discovered: This animal trusts me. She not sees me as a danger, and her concern adjustments to interest,” he says. “That is when the true pleasure comes and also you suppose, ‘Oh, my goodness, I am being let into the name of the game international of this wild animal’ — and that’s the reason when you are feeling on hearth.”
Foster chronicles his underwater encounters within the kelp woodland within the new Netflix movie, My Octopus Instructor, and the ebook, Sea Alternate.
Interview highlights
At the risks of diving off the western cape of South Africa
I’ve come very shut a couple of occasions to dropping my lifestyles. … I have been sucked into underwater caves. – Craig Foster
It is referred to as the “Cape of Storms” for a nice explanation why — monumental waves and one of the greatest browsing waves on the earth. And persons are terrified of sharks and massive animals and that more or less factor, which don’t seem to be if truth be told actually a threat in any respect. However the only factor this is very bad are those monumental seas. And I’ve come very shut a couple of occasions to dropping my lifestyles and I have been sucked into underwater caves. … So if you are devoted to diving on a daily basis, particularly, it’s a must to be very, very cautious and take a look at to learn the elements really well, attempt to learn the currents after which do not challenge into the ones very bad puts right through the ones occasions. There may be at all times some little position you’ll to find to get in, which is reasonably protected, but it surely took some time to be informed precisely how to do this.
On why he chooses to unfastened dive — with out a wetsuit or oxygen — in those extraordinarily chilly waters
You are feeling alive, you are feeling wakeful, you are feeling stimulated. However as a result of you’ll really feel that water for your pores and skin, you’ll really feel the slight temperature variations, you are feeling a lot nearer to nature. You are feeling extra amphibious, in some way. I love to contemplate at the amphibious nature of our humanness and diving on this method, with this technique, brings out that amphibious nature.
In the beginning, it took me reasonably a very long time [to get used to the cold]. … I take into accout shivering for approximately a 12 months, on a daily basis. After which sooner or later, I simply stopped shivering and I used to be like, “Wow, my frame is being used to this. I will be able to thermoregulate.” And I slowly began to determine methods to stay relaxed and stay heat. And naturally, your frame adapts. However the attention-grabbing factor is, if I have had a nasty day or I have not slept effectively or I have had an damage, I am going within the water and it is very tricky for me to thermoregulate. If I have had a really perfect day, I have slept effectively, I am feeling robust, I will be able to keep in for a long time, as much as two hours. But when I am compromised mentally, I will be able to now and again be chilly inside 20 mins. … I have spotted precisely the similar with people. The chilly is a type of a reflect to how you’re feeling mentally.
On what it is like diving within the underwater kelp woodland
It is in reality like being in an underwater woodland. … It is like being on this magical different international this is very other to any international that you’ll have observed on land, and [there are] animals dwelling in all other ranges of the woodland. A coral reef is 2 dimensional compared in some ways, and there may be super biodiversity and really unique animals. And since there may be such a lot of predators, many of those animals are very, very cryptic. So you’ll simply dive in a woodland … and no longer see an animal that is been staring at you nearly on a daily basis.
The joy for me has been to slowly discover the name of the game lives of many of those cryptic animals. My implausible octopus trainer, she helped me in some ways to discover lots of the ones lives, as a result of she’s in the course of this meals internet. And to understand her, it’s a must to know such a lot of animals that she preys on, and naturally her predators as effectively, after which all of the scavengers that come to her den. She’s this wonderful trainer in some ways for the opposite lives of the animals within the woodland.
At the octopus “armoring” by way of masking herself in rocks
What I discovered is that octopus, they have were given all forms of tactics of coping with predators. And naturally, you’ll have identified concerning the inking, you understand about the entire camouflage and the whole lot. However one of the vital closing accommodations that they do, if they are in the proper of atmosphere, they’ll all at once, very, in no time pick out up as much as 70 shells and stones and now and again even bits of algae and canopy their entire frame with them by way of turning their palms over their head since the head is the very delicate a part of an octopus anatomy. And if a predator bites or interferes with the pinnacle, there may be incessantly a actually giant downside. So with the suckers, they pick out up these kind of items after which in an excessively quick house of time — in seconds — they quilt themselves and they are all at once armored.
On what octopus suckers really feel like for your pores and skin
You would be shocked how extremely tough the suction is, and they’re lined in a type of octopus slime that makes it adhere extra strongly, however they’re very, very robust. I imply, in the event you attempt to pull immediately again when that animal is retaining you, it is actually very, very tricky and you’ll need to power it. So it’s a must to gently twist and switch if you want to head as much as have a breath of air, as a result of you do not need to drag too onerous on that animal. So it’s a must to more or less curl and twist to wreck that extremely tough suction.
On staring at the octopus start to decline
It used to be clearly tricky. You get on the subject of an animal like this and I used to be no doubt dreading [her death]. However on the similar time, I assume in many ways it is higher than a human demise, as a result of it is reasonably merciful. It is reasonably quick. … When she will get to the top of her lifestyles, she turns into senescent, senile. So her mind begins not to paintings so effectively. So she’s no longer absolutely acutely aware of what is going on, and that introduced some convenience.
On nonetheless visiting the octopus’ den after her demise and feeling her presence
She had a couple of dens however her primary den, the place she spent as a rule, I went to discuss with that den as of late, this morning. It is a nice feeling to head there. I simply dive down and more or less silently thank her for this implausible instructing that she’s given me.
What occurs is as soon as she strikes out of the den, it quickly fills up totally with sand. So it is principally only a rock edge. However what is so attention-grabbing is that different octopuses appear in an effort to come what may sense precisely the place she’s denned and they have got made a den in precisely that very same position. I have observed this at different websites as effectively. … Perhaps they [have] some implausible skill to sniff, as a result of then they have got to excavate and dig the entire den up; there is no signal of it having been there. I am certain in a couple of weeks or a month I will be able to to find every other octopus in precisely that very same position.

DAVE DAVIES, HOST:
That is FRESH AIR. I am Dave Davies, in for Terry Gross. There is a new movie which paperwork an odd however touching friendship. FRESH AIR manufacturer Sam Briger talked to the filmmaker. I’m going to let Sam take it from right here.
SAM BRIGER, BYLINE: Some of the heartening movies of the 12 months is concerning the dating between our visitor, filmmaker Craig Foster, and an octopus he befriends whilst diving off the Western Cape of South Africa. Foster have been burned out from years of operating on onerous nature movies and made up our minds he wanted a reset. Craig Foster vowed that he would dive with out a rainy swimsuit or oxygen tank on a daily basis for a 12 months into the cold waters close to the place he grew as much as discover the kelp woodland, an ecosystem teeming with lifestyles. It used to be there that he won the agree with of an octopus who allowed him into its international, the place Foster came upon issues about its lifestyles and his personal. Foster’s movie is known as “My Octopus Instructor,” and it is to be had on Netflix. He additionally has a ebook about his exploration of the kelp woodland referred to as “Sea Alternate.” Foster’s won over 60 global awards for his paintings in documentary movies. I spoke to him from his house in Cape The town.
Craig Foster, welcome to FRESH AIR.
CRAIG FOSTER: Thanks, Sam. Happy to be right here.
BRIGER: So this adventure started whilst you began diving within the waters of the Western Cape, close to the place you grew up, on a daily basis for a 12 months. What forced you to do this?
FOSTER: Neatly, I simply, you understand, I have been via an excessively, very busy time. I felt drained, missing force. I used to be burnt out. And my earliest recollections, my private and maximum tough recollections had been of this implausible coast and diving in what I name my magical adolescence woodland, the Nice African Sea Wooded area, this underwater woodland. So it used to be a herbal position for me to head, simply to stay going into that water on a daily basis. And as I did that day to day, I slowly began to get my power again and discovered that there used to be this, you understand, entire new method of having a look at this underwater woodland. And I began to come back alive once more.
BRIGER: Those don’t seem to be pleasant waters. Within the film, you spot those large waves crashing upon the shore rocks. And we see you within the water. And you appear to be you are being driven about by way of those waves. You already know, you glance beautiful inclined. What are the perils of diving right here?
FOSTER: So you are proper. It is referred to as the Cape of Storms for a nice explanation why. They are monumental, monumental waves and one of the greatest browsing waves on the earth. And, you understand, persons are terrified of sharks and massive animals and that more or less factor, which don’t seem to be if truth be told actually a threat in any respect. However the only factor this is very bad are those monumental seas. And I’ve come very shut a couple of occasions to dropping my lifestyles and feature been sucked into underwater caves and this type of factor. So in case you are devoted to diving on a daily basis particularly, it’s a must to be very, very cautious and take a look at to learn the elements really well, attempt to learn the currents. After which, you understand, do not challenge into the ones very bad puts right through the ones occasions. There may be at all times some little position you’ll to find to get by which is reasonably protected, but it surely took some time to be informed precisely how to do this.
BRIGER: And those are chilly waters. It appears like they are able to get to 46 levels Fahrenheit. However you made a decision to dive with out a wetsuit and with out an oxygen tank. Why is that?
FOSTER: You already know, it is attention-grabbing. Numerous other folks first of all stated, you understand, what – why are you riding with out a wetsuit? It is loopy. And through the years, I have taken many of us into the water to turn them what it is love to pores and skin dive, to unfastened dive with out with a minimum apparatus. And, Sam, what it does is, initially, the chilly if truth be told adjustments the chemical nature for your mind. It pushes numerous feel-good chemical substances into the mind. So you are feeling alive. You are feeling wakeful. You are feeling stimulated. However as a result of you’ll really feel that water for your pores and skin, you’ll really feel this slight temperature variations. You are feeling a lot nearer to nature. You are feeling extra amphibious in some way.
I love to contemplate at the amphibious nature of our humanness, and diving on this method with this technique brings out that amphibious nature. So there are if truth be told reasonably numerous benefits to it. And what it does in the end is this chilly tension if truth be told places a definite tension at the immune device that makes it reasonably so much more potent. So that you get a lot more healthy right through that procedure.
BRIGER: However did it take you some time to acclimate to swimming in the ones temperatures? How a lot time would you if truth be told be within the water?
FOSTER: So to start with, it took me reasonably a very long time, I’ve to confess. Other folks have appear to have acclimatized a lot more briefly, those that I have due to this fact taken in. So I take into accout shivering for approximately a 12 months on a daily basis. After which sooner or later, I simply stopped shivering. And I used to be like, wow, my frame is being used to this. I will be able to thermoregulate. And I slowly began to determine methods to stay relaxed and stay heat. And, in fact, your frame adapts.
However, you understand, the attention-grabbing factor, Sam, is that if I have had a nasty day or I have not slept effectively or I have had an damage, I am going within the water and it is very tricky for me to thermoregulate. If I have had a really perfect day, I have slept effectively, I am feeling robust, I will be able to stand for a long time, as much as two hours. But when I am compromised mentally, I will be able to now and again be chilly inside 20 mins. So it is very attention-grabbing. And I have spotted precisely the similar with people. It is – the chilly is a type of a reflect to, how are you feeling mentally?
BRIGER: And what about retaining your breath? Like to start with, how lengthy may you keep below water, and the way had been you ready to make stronger that? Was once it simply by apply that you were given higher?
FOSTER: Sure, in fact. Indisputably by way of simply going on a daily basis, practising your breath naturally will get higher. After which I now and again do respiring workouts on land, seeing how lengthy I will be able to dangle my breath, that more or less factor. However it is very other. What other folks do not understand is that if you are filming and you are operating below water and you are shifting your frame, you are the usage of up reasonably numerous oxygen. I will be able to’t do the vintage unfastened diving methodology of respiring up at the floor for mins and enjoyable my entire frame and simply taking one lengthy, implausible deep dive.
I am operating, you understand, with those implausible animals within the sea woodland. So I want to be going up and down so much as a result of I want to be with them. So I have needed to get nice at having only one or two breaths on the floor and happening for so long as I will be able to, then one or two breaths of the skin and happening lengthy so long as I will be able to. So it is a other option to those lengthy one-breath unfastened divers you spot doing those implausible depths.
BRIGER: So right through those dives, you find this specifically stunning kelp woodland. What makes a kelp woodland particular? Is it form of like a coral reef in its variety of sea lifestyles?
FOSTER: It is totally other to a coral reef. So if you’ll believe, it is, you understand, it is in reality like being in an underwater woodland. The holdfasts are just like the roots which can be caught to the rock. And so they had lengthy stipes, that are just like the stems of the tree. After which at the most sensible are the leaves, the blade and the leaves of the tree that flow at the most sensible. And the stipe is stuffed with fuel, so it floats. And the sunshine, you understand, sprinkles in the course of the most sensible of those leaves. And also you get those implausible shafts of sunshine. It is like being on this magic entire different international this is very other to any international that you’ll have observed on land and the animals dwelling in all other ranges of the forests.
A coral reef is 2 dimensional compared in some ways, and there may be super biodiversity and really unique animals. And since there may be such a lot of predators, many of those animals are very, very cryptic. So you’ll simply dive in a woodland, which came about to me for years, and no longer see an animal that is been staring at you nearly on a daily basis. And the thrill, for me, has been to slowly discover the name of the game lives of many of those cryptic animals.
And my implausible octopus trainer, she helped me in some ways to discover lots of the ones lives as a result of she’s in the course of this meals internet. And to understand her, it’s a must to know such a lot of animals that she preys on and naturally, her predators as effectively after which all of the scavengers that come to her den. And he or she’s this wonderful trainer in some ways for the opposite lives of the animals within the woodland.
BRIGER: Neatly, let’s communicate concerning the octopus. So sooner or later you are diving within the kelp woodland and you spot this peculiar assortment, like, it is like a ball of shells and rocks. And there may be an octopus in there ‘motive the octopus swims away sooner or later, and it is been retaining all of the shells and rocks towards its frame masking itself. And it appears like this habits had no longer been documented sooner than. What have you ever realized about this habits?
FOSTER: Sure, you are completely proper, I imply, I name this habits armoring. And what I have realized is that – I imply, this took reasonably some time to determine. And, you understand, I am fortunate sufficient additionally to paintings with wonderful scientists who lend a hand me determine numerous those mysteries that I practice within the woodland, and a few of them dive with me – my professor Charles Griffiths, who is this, you understand, glorious mentor – Dr. Jannes Landschoff, he is a gorgeous younger marine biologist who dives with me so much – after which professor Jennifer Mather, who is a octopus specialist.
So – and I am going and picture these items, after which I speak about issues with those glorious scientists, and we strive and determine all of it out. And what I discovered is that octopus, you understand, they have were given all forms of tactics of coping with predators. And naturally, you’ll have identified concerning the inking. You would – you understand, you understand about the entire camouflage and the whole lot.
However one of the vital closing accommodations that they do, if they are in the proper of atmosphere, they’ll all at once very, in no time pick out up as much as 70 shells and stones and now and again even bits of algae and canopy their entire frame with them by way of turning their palms over their head. Since the head is the very delicate a part of an octopus’s anatomy. And if a predator bites or interferes with the pinnacle, there may be incessantly a actually giant downside.
So with the suckers, they pick out up these kind of items, after which in an excessively quick house of time, within the seconds, they quilt themselves and they are all at once armored. And it is a – you understand, in evolutionary point of view, this animal has discarded its shell to change into extra of a liquid creature, so there may be numerous benefits to being a liquid creature. After which, on this implausible method, has discovered a method to briefly create this transient shell, onerous shell that, effectively, can deter a predator.
BRIGER: Yeah, it is wonderful. And I believe, you understand, right through your time within the kelp woodland, you are simply fascinated with this creature. And so that you get started visiting it on a daily basis, and also you if truth be told achieve its agree with. And it turns into relaxed following you round, and it allows you to practice it round. And it could even connect to you and swim with you. Had you ever had an interplay like this with a wild creature sooner than?
FOSTER: No longer any place at this degree as a result of I have been diving for years. I have been diving since I used to be Three years outdated. I am now 52. And within the closing 9 years, I have dived each unmarried day as a dedication to figuring out the sea. So I’ve had interesting encounters with more than a few animals, animals that experience made up our minds to come back and get in touch with me. However it is most commonly fleeting. You already know, it occurs simply on one instance, on sooner or later. And it is more or less mysterious, and it is attention-grabbing.
However this used to be other in that, you understand, this used to be over an extended time frame that this agree with and this bodily touch constructed up. Occasionally when she’d eaten or when she used to be – you understand, they are reasonably moody. Occasionally she did not need to have touch. So it wasn’t adore it used to be going down completely on a daily basis, however no doubt had many odd reports along with her many, repeatedly. I could not, you understand, movie them as effectively. So, you understand, the movie is only a slice, actually, of the enjoy of being with this implausible creature and studying from her.
BRIGER: Neatly, let’s take a brief wreck right here. I am talking with Craig Foster about his movie “My Octopus Instructor,” which is to be had to look at on Netflix. Extra after wreck. That is FRESH AIR.
(SOUNDBITE OF LOOP 2.4.3’S “ZODIAC DUST”)
BRIGER: That is FRESH AIR. In case you are simply becoming a member of us, our visitor is Craig Foster. His movie “My Octopus Instructor” is concerning the agree with he won of an octopus whilst diving on a daily basis for a 12 months into the kelp woodland off the Western Cape of South Africa. You’ll to find the film on Netflix.
So you are fascinated with this octopus and making a decision that you will move discuss with it on a daily basis and practice it. And at one level, the octopus if truth be told reaches out and touches you. What did that second really feel like?
FOSTER: You already know, that is clearly a unique second when that animal comes to a decision to make that first touch. There is something particular when that occurs evidently. And, you understand, different octopuses have accomplished that to me as effectively, but it surely used to be come what may other along with her. It is unimaginable to provide an explanation for. However you should understand, Sam, she’s nonetheless retaining on with all her palms. It is simply that one arm that she’s sending out. The true second when I used to be, like, simply totally blown away used to be when she got here out the den proper in entrance of me, after which there is no palms retaining again. That is after I discovered this animal trusts me. She not sees me as a danger. And her concern adjustments to interest. That is the giant second.
The actually uncommon and particular factor is when the agree with bureaucracy, and that could be a completely other state of affairs. When that animal comes out, and there is no – its entire frame is inclined. And he or she is going about searching and doing her implausible behaviors. That is when the true pleasure comes. And also you suppose, oh, my goodness, I am being let into the name of the game international of this wild animal. And that is the reason when you are feeling on hearth.
BRIGER: So when the octopus touches you, what do the suckers really feel like?
FOSTER: You would be shocked how extremely tough the suction is. And they’re lined in a type of octopus slime that makes it even adhere extra strongly. However they’re very, very robust. I imply, in the event you attempt to pull immediately again when that animal is retaining you, it is actually very, very tricky. And you’ll need to power it. So it’s a must to gently twist and switch if you want to head as much as have a breath of air as a result of you do not need to drag too onerous on that animal. So it’s a must to more or less curl and twist to wreck that extremely tough suction.
BRIGER: With a creature like this that turns out so international to us, I believe it is actually complicated to know why it is doing what it is doing. However it sort of feels just like the octopus used to be as fascinated by you as you had been in it. Why do you suppose that is the case?
FOSTER: In order you are saying, Sam, it is very tricky to understand what a cephalopod, an octopus, is pondering. And I do not fake to understand what she used to be pondering. However they’re very curious by way of nature. So that they oscillate between concern and interest. And particularly on this Nice African Sea Wooded area right here at the tip of Africa the place there may be such a lot of predators, octopuses generally tend to head extra at the concern aspect of items. So many of the octopuses I have encountered are doing a little job or doing a little habits. Once they see me and my presence is within the water, they’ll discontinue and take a look at and conceal away and break out. And if I – if they are at their den, they will simply move perhaps deep into the den.
So it is just after some time this animal discovered, OK, this particular person – and take into accout, they are able to acknowledge person other folks, that is been proved – understand I am not a danger. After which, you understand, the entire recreation adjustments as a result of that concern is triumph over by way of that implausible interest. And, you understand, what is that this creature? How does this creature really feel? And take into accout, the suckers can style as effectively. So how does the flesh – how does it – what it tastes like. And it used to be interesting to peer, you understand, how she now and again used me in her searching technique. So she’d use my frame now and again to corral the prey, that more or less factor. So perhaps I used to be reasonably helpful in that method now and again.
BRIGER: (Laughter) Yeah.
FOSTER: It isn’t simple to understand what she’s pondering.
BRIGER: Neatly, I’ve a query about that. Is it simple, or is it a entice to begin anthropomorphizing a creature like this if you find yourself seeking to perceive its habits?
FOSTER: I believe it’s a must to be very cautious of that as a result of she’s – you understand, she’s 200 million years clear of us at the evolutionary scale. So in many ways, she has this very historical, historical thoughts, however her neural make-up is, in many ways, very similar to ours. So there’s a chance that she may really feel sure feelings. However how the ones are interpreted – and in addition, what is very attention-grabbing, Sam, is that two-thirds of her cognition is out of doors of her mind, in her palms. And so her palms have this exterior cognition.
And, you understand, it is a onerous rapid to get our ideas round how that every one works. So you are coping with, you understand, an excessively other creature in some ways. However in all probability the underlying nature of cognition isn’t that dissimilar. That is additionally at the back of one’s thoughts. So that you – it is mysterious, and that’s the reason what makes it so attention-grabbing. And that is the reason why I will be able to learn about those animals for the remainder of my lifestyles. And I handiest know a tiny bit of ways they paintings.
BRIGER: We want to take every other quick wreck right here. We are talking with Craig Foster about his movie, “My Octopus Instructor.” You’ll watch it on Netflix. We’re going to be again after a brief wreck. That is FRESH AIR.
(SOUNDBITE OF CLEVELAND ORCHESTRA, CLEVELAND ORCHESTRA CHORUS, GARETH MORRELL AND PIERRE BOULEZ’S “NOTURNES: III. SIRENES”)
BRIGER: That is FRESH AIR. I am Sam Briger, sitting in for Terry Gross. Let’s get again to my interview with filmmaker Craig Foster about his new film, “My Octopus Instructor.” Whilst Foster used to be diving within the kelp woodland off the coast of South Africa, he won the agree with of a wild octopus that allowed him to discuss with it on a daily basis and know about its habits. Foster used to be provide for approximately 80% of the octopus’ lifestyles. “My Octopus Instructor” is to be had to look at on Netflix.
So I might like to speak extra about those outstanding creatures. You already know, what actually amazes me is their pores and skin. They have got this nearly prompt skill to modify their colour as camouflage. So are you able to let us know a little bit bit about how that works? Like, how are they sensing the colours round them? As a result of I believe I learn that octopus are colour blind.
FOSTER: Yeah. You already know, you might have accomplished your analysis. That is the peculiar factor is, how the heck can an animal that is colour blind fit its colour so completely and camouflage with its background? I imply, it is identical to, you understand, what on earth is happening there? And so far as I will be able to perceive, we do not absolutely know the way that is conceivable. However there are some attention-grabbing clues. And I believe cuttlefish supply us – you understand, cuttlefish are intently associated with octopus.
And I believe if I am – discuss below correction – however they are able to if truth be told hack colour by way of having a look at the edges by way of having this chromatic shift of their eyes. They have were given those peculiar formed eyes. And they are able to if truth be told see colour, despite the fact that they are colour blind on this chromatic shift. There also are opsins of their pores and skin that may locate some type of gentle or colour. However it’s reasonably an out of this world factor that an animal this is, you understand, necessarily seeing in black and white can camouflage in colour in such an odd method. And they have were given more than a few – the principle factor they use are chromatophores, that are like ink sacs that they are able to shrink or enlarge to modify the colour. After which they have were given more than a few layers beneath that of various ways in which they are able to make themselves glance – I believe they are referred to as iridophores – nearly translucent and sparkly.
So they have were given those layers of – however what I realized used to be one thing that used to be very attention-grabbing is if an animal used to be on a floor and it used to be scuffling with to compare the colour of that floor, what I discovered so interesting used to be as a substitute of seeking to get one thing that it could not reasonably get proper, it could to find every other object, perhaps every other animal, every other mollusk or every other plant on that floor and quite mimic that. So the octopus gave the impression of simply every other abalone or simply every other piece of algae at the substrate. You with me?
So you’ll – that is odd intelligence. So I am scuffling with. I am scuffling with. I am suffering to compare my floor. OK. There may be an object over there. I will fit that and faux that I am a work of algae or an impenetrable abalone, after which the predator would possibly not see me. I imply, that is implausible intelligence. And those are the type of issues I realized over the time along with her.
BRIGER: The surface of the octopus additionally appears to be converting always, adore it’s easy or it seems to be beaded. They may be able to span their palms or contract them. They now and again will make little horns at the most sensible of its head. Can we perceive what that is all about?
FOSTER: Sure. So there are muscle mass all over the place the octopus, and it could actually pull up its pores and skin into those implausible shapes with those little muscle mass, and that’s the reason why I will be able to develop the horns at the head to seem fierce. Or it could actually – if it is on a floor this is very rugged, it could actually pull its pores and skin up into having a look very beautiful to compare that floor. Steadily a easy floor could make its pores and skin totally easy. So it has got super – and it could actually, as you are saying, telescope its arm to I believe a minimum of two times the duration of the standard arm.
So it is actually a liquid creature that may squeeze in the course of the tiniest, tiniest gaps. And you’ll believe in a – as if you find yourself being chased, like I witnessed, you understand, a crab hunt. What does that crab if you find yourself being chased by way of a liquid animal that may simply actually squeeze itself via any tiny little crack and pay money for you? It is a very – it is horrifying.
BRIGER: Yeah. You obviously felt very on the subject of the octopus. How did making a decision whether or not or no longer you can intercede in its lifestyles if it used to be at risk?
FOSTER: If you find yourself getting to understand all of the animals within the Nice African Sea Wooded area, you are getting to understand all of her prey species and that she will be able to kill and devour over 50 various kinds of prey. You might be additionally getting to understand her predators. And her primary predator on this space I used to be had been those pajama sharks, however, in fact, you get to understand those animals really well. You watch the adults lay their eggs. You watch the ones eggs and that child shark growing in there. And then you definitely see a predator simply sooner than that shark’s about to hatch devour that tiny shark out of the egg.
So that you get shut no longer handiest on your glorious octopus trainer, however you get on the subject of those stunning sharks, and you spot how tricky their lives are. And also you get to peer how they their combat to continue to exist. And they are a far longer-lived animal. So it is tougher for them. So that you expand this empathy for the entire dwelling ecosystem. And also you – it is very onerous for then you definitely to come back in and get started interfering with one thing that is stored its stability for tens of millions of years. It simply does not appear proper.
BRIGER: There may be this second that is actually onerous to look at within the movie the place a pajama shark if truth be told assaults the octopus and rips off one in all her palms. And fortuitously, the octopus recovers. However are you able to let us know what you had been going via when that came about?
FOSTER: Certain. I imply, it is simply – in a – it should understand it’s going down so rapid. And it is swirling ocean. And, you understand, I used to be clearly simply terrified for her. She went proper deep below a rock. And I assumed that she’d escaped and used to be high quality. And I used to be completely surprised when that pyjama shark used to be ready to nearly burrow its, you understand, pointed head proper in there, take hold of dangle of her arm, after which simply do that terrifying demise roll, like a crocodile demise roll, and twist and take her arm off. And it used to be a surprise and, yeah, a maximum unsightly enjoy.
BRIGER: Does it deplete numerous power for an octopus to regrow an arm like that?
FOSTER: It is a honest quantity of power to regrow. However what is wonderful is that a couple of 3rd of all of the octopus on this nice African sea woodland have lacking limbs. So it is one thing that occurs so much and that it is – you understand, they’re very in a position to regrowing the ones limbs. And they are able to continue to exist, if truth be told, I believe reasonably simply. It is in the event that they get bitten within the head, that is when the issues – you understand, then it is a lot more critical.
BRIGER: Let’s take every other quick wreck right here. My visitor is Craig Foster. His movie, “My Octopus Instructor,” will also be observed on Netflix. Extra in a while. That is FRESH AIR.
(SOUNDBITE OF GAIA WILMER OCTET’S “MIGRATIONS”)
BRIGER: That is FRESH AIR. In case you are simply becoming a member of us, we are speaking with filmmaker Craig Foster about his film, “My Octopus Instructor,” which you’ll to find on Netflix.
So, you understand, the typical octopus has an attractive quick lifestyles span of a couple of 12 months. And also you had – you understand, you discovered you’ll been spending numerous time with this octopus and obviously her lifespan used to be coming to an finish. Did you begin to really feel ambivalent about your journeys to the sea right through the ones closing days? Like, had been you having a look ahead to seeing her but in addition dreading the top?
FOSTER: Yeah. It used to be clearly tricky. You already know, you get on the subject of an animal like this, and I used to be no doubt dreading that. However on the similar time, I imply, I assume in many ways it is higher than a human demise as a result of it is reasonably merciful. It is reasonably quick. And in addition what occurs when she will get to the top of her lifestyles, she turns into senescent – senile, so her mind begins not to paintings so effectively. So she’s no longer absolutely acutely aware of what is going on, and that introduced some convenience.
BRIGER: So we see the octopus mate, and a male octopus comes alongside. And it is to start with simply sitting close to her, after which it looks as if one in all its palms is extending out to her. What is mating like for an octopus? It regarded beautiful transactional.
FOSTER: Sure. I imply, it may be very bad now and again, you understand, particularly if the feminine is greater. She may also kill the male after mating. So now and again he is very wary. And that is the reason why he is, like, extending the arm proper out. Like, there may be this tiny little penis at the finish of the arm. And so it is – yeah. They are very anti-social animals. So it is not some nice love affair, that is evidently.
BRIGER: (Laughter) And does this procedure sign the top of the lifestyles cycle for each the male and the feminine?
FOSTER: Proper. So the male additionally begins to become worse reasonably briefly after the mating. It is referred to as – I believe the phrase is semelparous. And plenty of animals, particularly bugs, have the similar procedure.
BRIGER: So the octopus hatches her young children, and at this level, she’s form of been retaining directly to her lifestyles power to form of get to that time, after which she’s form of on the finish of her lifestyles. And her power is long past, and her frame washes out of her den. And there may be this extremely stunning however unhappy symbol that you’ve got of her laying at the sea ground. And her eyes are closed, and she or he’s gotten actually faded, so she will be able to not form of exchange the colour of her pores and skin. And, like, her frame’s swaying a little bit bit with the motion of the water. It is a shockingly shifting shot. I used to be simply questioning what you felt taking that shot.
FOSTER: Yeah. I imply, it is an – it is maximum tricky – very, very tricky. And it is onerous to form of specific it with out getting a little emotional, so I nearly check out not to to think about that an excessive amount of as it makes me really feel unhappy – so very tricky – yeah, very tricky.
BRIGER: Within the film, you are saying that you just nonetheless discuss with her den after her demise and also you form of flow above it and really feel her presence. Do you continue to do this? Do you discuss with her den?
FOSTER: Humorous sufficient, Sam, I went to her – you understand, she had a couple of dens, however her primary den the place she spent the as a rule, I went to discuss with that den as of late this morning. Yeah, it is simply a really perfect feeling, you understand, to head there. And, you understand, I simply dive down and more or less silently thank her for this implausible instructing that she’s given me. And what is so attention-grabbing is that, you understand, I have observed – there used to be not anything – what occurs is as soon as she strikes out of the den, it quickly fills up totally with sand. So it is principally only a rock edge.
However what is so attention-grabbing is that different octopuses appear in an effort to come what may sense precisely the place she’s denned stand and they have got made a den in precisely that very same position. And I have observed this at different den websites as effectively. So there is something – perhaps they are able to scent – there may be some implausible skill to sniff as a result of then they have got to, in fact, excavate and dig the entire den out. There is not any signal of it having been there. And so I am certain in a couple of weeks or a month, I will be able to to find every other octopus in that very same – precisely that very same position. And it is not, you understand, 20 or 30 centimeters away. It is in the similar position.
BRIGER: So, you understand, you are seeking to get safe standing for the ocean forests alongside the Western Cape. What are one of the threats to this ecosystem?
FOSTER: There are a couple of threats to the ecosystem. Commercial fishing, I believe, is an enormous danger as is, and it is a danger to the entire ocean. We have now air pollution as, you understand, a major danger, particularly rivers being polluted and chemical substances operating into the ocean, which, you understand, is, once more, a global downside. We have now a slightly critical poaching downside, particularly with abalone and to some extent with rock lobster and overfishing of particularly reef fish. Lots of them are endangered, if no longer nearly on the finish in their lives – in their species. So they’re actually in a construction – coastal construction. Other people short of to position up resorts and massive complexes proper at the seaside is, you understand, is actually a demise knell for the surroundings. So there are a couple of threats, even the specter of mining the sea mattress. You already know, so there are sadly a couple of threats.
And what we attempt to do is to get this – we are calling it the Nice African Sea Wooded area – have it get to be identified international, just like the Amazon or the Serengeti or the Nice Barrier Reef, the Nice African Sea Wooded area, as it is without doubt one of the largest ecosystems on the earth. And it is nonetheless, to a big stage, intact. The habitat’s intact. Most of the species had been knocked proper down. We desperately want to regenerate lots of the ones species. However that is – there may be hope right here. So what we’re seeking to do is to turn simply how odd this dwelling device is. And it’s completely important for the well-being of each human on Earth. And we if truth be told breathe on account of it, particularly on account of the sea. So all of us want to come in combination and actually check out to determine some way of no longer simply being sustainable however if truth be told regenerate those wild programs as a result of they’re the immune programs of our planet. The biodiversity is the object that assists in keeping the arena wholesome and that assists in keeping people wholesome. And once you get that into your head, then you can need to do the whole lot to stay that biodiversity and all the ones animal species in position.
BRIGER: Are you continue to diving there on a daily basis?
FOSTER: Oh, sure, sure. I used to be in as of late and I’m going to be in day after today. You already know, even though I’ve an extended operating day, I’m going to attempt to stand up very, very early and get in. It is simply one thing that I actually – makes me really feel nice.
BRIGER: Craig Foster, thank you such a lot for approaching FRESH AIR.
FOSTER: It is been a really perfect excitement, Sam, chatting with you, and I actually recognize it.
DAVIES: Craig Foster’s movie is “My Octopus Instructor.” It may be observed on Netflix. He spoke with FRESH AIR manufacturer Sam Briger. Bobbing up, David Bianculli opinions Aaron Sorkin’s latest drama, “The Trial Of The Chicago 7.” That is FRESH AIR.
