Years of close contact made Foster experience wild animals as kin and teachers. He believes these bonds reduce how much he demands from human relationships, and suggests that losing the multispecies relationships common through prehistory may redirect additional pressure toward partners, friends, and family.

Many marine animals allowed close contact because they did not treat him as prey
Repeated relationships made the creatures feel like family
Foster says his relationship with his wife improved
He frames the loss of multispecies bonds as a possible source of pressure on human bonds

“it feels like family, like kin in the water after a while”
Craig Foster · 34:30

“it mostly goes, I think, to a bit more pressure on human relationships.”

Biodiversity Protects Every Other Investment

Foster argues that climate action receives necessary attention but biodiversity receives too little. He calls plant and animal species the human immune and life-support system, making ecological collapse a threat that would erase the value of property, finance, enterprise, and future plans.

Sea Change Project studies and tells stories about 1,001 kelp-forest animals
Foster says climate work is critical and must continue
He frames biodiversity as the foundation beneath all economic activity
Phytoplankton collapse is his stark example of dependence on living systems
He asks why governments and businesses invest too little in regeneration

“they actually form our immune system. They are the life support system of everything.”
Craig Foster · 1:33:30

“That investment is worth zero if biodiversity collapses.”

How a Tracker Follows an Animal Without Seeing Its Tracks

Foster explains that persistence hunting is a rare, sacred, dangerous hunt made possible partly because humans can cool themselves by sweating while prey overheats. In the hunt he filmed, master tracker Karoha spent most of the pursuit without following physical tracks, appearing to integrate sensory information through his whole body.

The filmed hunt lasted more than four hours in extreme heat
Persistence hunting is rare and dangerous for hunters with little water
Karoha crossed physical tracks while continuing to locate the kudu
Foster compares the embodied skill with Indigenous ocean navigation

“It's basically because we can sweat and keep ourselves cool, whereas those animals overheat.”
Craig Foster · 10:00

“his body is like a radar system.”

Why Deep Wild Connection Can Produce Spontaneous Joy

Foster describes laughter arising spontaneously in San trackers while they move through the landscape. Researchers he worked with called this apparent joy in deeply connected Indigenous societies “Wilderness Rapture,” although Foster notes that joy also varies between individuals and should not be romanticized as universal.

The laughter was not a reaction to an external joke
Foster associates it with being deeply embedded in the natural world
The joy coexists with poverty and difficult conditions
He acknowledges that people in modern society can also be very joyful

“it's this primal joy of being in that space and being so connected to the wild.”
Craig Foster · 14:30

“There's an extraordinary sense of joy that seems to be connected to being very embedded in the natural world.”

The Thousands of Signs Hidden Underwater

Foster initially thought underwater tracking was impossible because swells erase marks. Over a decade he learned to read mollusk slime trails, marks on animals, drill holes, bite marks, shell shine, and other traces to infer who had been present, what had eaten what, and when events occurred.

Mollusk slime collects tiny sand particles and leaves subtle trails
Marks on a ray can indicate animal interactions and resting time
Predator drill holes and bite marks identify ecological events
Shell shininess and other details help estimate timing
Foster says the wider aquatic tracking system took ten years to assemble

“And then I started to notice the slime trails.”
Craig Foster · 30:30

“There are literally thousands and thousands of these subtle signs but it's taken me 10 years to slowly put together”

The Amphibious Soul Between Wildness and Technology

Foster uses the “amphibious soul” to describe living between a wild evolutionary self and a technologically comfortable tame self. He rejects both total retreat and total immersion in modernity, seeking a balance that leaves him calmer and more centered without denying his love of science, coffee, film, and technology.

Foster felt he was living a double life
He sees humans as wild animals shaped by deep evolution
A fully wild return is no longer available
Too much tame-world exposure leaves his nervous system activated and disrupts sleep
Practices that retain wildness help him feel centered

“Part of my life was wild and connected to three million years of deep evolution in all my incredible ancestors from Africa. And then part…”
Craig Foster · 44:30

“Because you can't go back to a fully wild existence, that door is completely shut for us now.”

The Octopus That Turned the Camera Around

While Foster and marine biologist Jannes were studying rare shaggy sea hares, a curious octopus took Foster's camera into its den. It turned the still-recording camera toward the humans, creating footage from the animal's physical perspective and prompting them to reconsider humanity's place in the wild world.

Foster waited rather than forcibly retrieving the camera and disturbing the animal
The octopus manipulated the camera and filmed the observers
The footage made the animal's perspective emotionally immediate
Foster and Jannes placed the octopus first and humans last in their 1,001-species project

“this curious octopus looked at the camera, then turned the camera and started filming us.”
Craig Foster · 1:54:00

“it had this amazingly profound effect on us that it is suddenly looking through this world from the octopus's perspective.”

The Wild Otter That Reached Into Foster's Mask

During a freezing dive when Foster was questioning his daily practice, a rare Cape clawless otter approached him. He stayed still and avoided facing it directly; the animal touched his feet, moved along his body, touched his face, and later followed him into the shallows while calling.

Foster interpreted his mouth and front as potentially threatening to the otter
Remaining still allowed the shy animal to choose contact
The encounter answered his doubts about continuing the dives
Research later led him to the history of humans hunting cooperatively with wild otters
He does not claim to know whether this otter carried any such deep memory

“my instinct was to keep still and not turn to face the animal”
Craig Foster · 37:00

“it reached out and started touching my face.”

Three Years of Clues Pointed to an Urchin Under the Sand

After years of finding only dead heart-urchin shells, Foster relaxed his deliberate search and felt an answer surface: the animal was under the sand. Digging confirmed the inference, after which he could consciously identify the subtle detritus traps that made the animals easier to find.

Foster searched for a living heart urchin for three years
His conscious mind had not recognized all the signs he was absorbing
A relaxed inference directed him beneath the sand
The successful discovery allowed him to reconstruct the clues explicitly
He now finds the animals by recognizing their subtle detritus traps

“some of which my conscious mind is not recognizing, but the unconscious is taking everything in.”

“It's underneath the sand. And I dug about that deep in the sand and out came this incredible live heart urchin”

The Fire That Separated Foster's House From His Home

An electrical fire destroyed the house Foster, his wife, and his son had nurtured for sixteen years. After escaping with his son and a friend, Foster entered the kelp forest and realized that the functioning biosphere felt like his deeper home, while the physical house could be rebuilt.

The house and nearly all possessions were lost within hours
Friends' care helped the family move through the initial shock
Foster, his son, and his son's friend escaped without serious injury
The ocean and healthy biosphere became his deeper definition of home
He distinguishes that enduring home from the house he is rebuilding

“from one hour to two hours later, I had this beautiful home that my wife and I and my son had nurtured for 16 years…”
Craig Foster · 1:12:30

When My Octopus Teacher's Success Shattered Foster's Sleep

The sudden global reach of My Octopus Teacher brought overwhelming attention, constant contact, awards, and severe insomnia. Foster says he gradually rebuilt his nervous system through gentle contact with the sea, cold, tracking, breathing, and lessons from Indigenous people, while the attention also naturally faded when he stopped feeding it.

Foster expected modest interest rather than exposure in more than 100 million homes
Incoming contact reached roughly one email every four seconds
He sometimes slept only minutes per night for weeks and months
He lost weight and could initially tolerate only gentle nature exposure
Letters from people helped by the film mattered more to him than awards
He is grateful for what he learned but would not want to repeat the trauma

“I slept extremely badly, sometimes just a few minutes a night for weeks and for months”
Craig Foster · 1:23:30

“I slowly used wild nature, just going into that sea.”

Foster's Critical Separation Between Breath Practice and Diving

Foster describes a morning breath-hold practice but explicitly separates it from freediving because breathing techniques near water can be dangerous. He also treats changes in cold tolerance as feedback: poor sleep, stress, or illness can sharply reduce his ability to thermoregulate.

His dry practice includes deep breathing followed by three-to-five-minute holds
He repeats the hold three or four times
He leaves at least half an hour between breathing techniques and entering water
Before a freedive he takes only two or three deep breaths
Stress, illness, and sleep loss can radically change cold tolerance

“one's got to be very careful never to do any of these breathing techniques close to actually going in the water.”
Craig Foster · 27:30

“It's amazing how the body's ability to thermoregulate tells you how your mind is feeling”

The Calm That Lasted Months After One Wild Immersion

A month at a remote, near-pristine research station left Foster calmer, more present, and more at home for months afterward. He proposes that abundant biodiversity signals safety to the ancient, sensory parts of the human psyche, while biologically depleted surroundings may signal scarcity even when modern supplies are available.

The island environment was densely populated with animals
The psychological effect persisted for months
Foster links the calm to perceived ecological health and available food
He argues that the older nervous system does not understand supermarkets
The effect depends on both available nature and a person's access and experience

“It was as if I'd been given some magic elixir and I felt so much calmer, so much more present, so much more at home.”

Finding a New Species Is Easier Than Naming One

Foster's collaborators have named and identified three shrimp species, including one associated with octopus dens. He says discovering unfamiliar species in the region can be surprisingly easy, while formally describing and naming them requires so much work that researchers may hesitate to inspect another candidate.

The team has named and identified three shrimp species
One shrimp probably has a mutual relationship with cephalopods inside octopus dens
The local marine environment still makes new-species encounters common
Taxonomic description is the labor-intensive bottleneck

“We've lost count, we've actually been able to name and identify three species of shrimp.”
Craig Foster · 1:04:00

“It's the naming of it that's an enormously difficult job.”

Why Rapt Attention Gave Childhood Stories Meaning

Foster says a child most needs to know they are truly loved, supported by dedicated time and shared activities both parent and child enjoy. His grandmother and great-grandmother expressed that love by giving complete attention to his childhood stories, making those experiences feel meaningful and creating support he can still draw on.

Foster tried to transmit love of nature by embodying it rather than pushing lessons
He prioritized focused time and mutually enjoyable activities with his son
His elders listened to childhood stories with rapt attention
Undistracted interest made those stories feel meaningful
He still draws strength from the unconditional love he experienced

“if they truly know that you really love them, that's the most critical thing.”
Craig Foster · 1:17:00

“there's something about that focus and not being distracted with other things that was immensely powerful, that gave our childhood meaning.”
