After years of swimming every day in the freezing ocean at the tip of Africa, Craig Foster meets an unlikely teacher: a young octopus who displays remarkable curiosity. Visiting her den and tracking her movements for months on end he eventually wins the animal’s trust and they develop a never-before-seen bond between human and wild animal.
This movie contains 6 potentially triggering events.
"Tracking" an animal is not quite the same thing as stalking, but there are some similarities that could be difficult for someone if that viewer is especially sensitive to such topics.
The perspective character (narrator, filmmaker) does develop a daily habit of underwater diving, that his body becomes acclimated to. It is depicted as a positive, wholesome ongoing-choice to participate in and show up at a place rather than as a harmful substance-dependence cycle, but it is definitely depicted as a habit he comes to depend on nonetheless.
It's an amazing documentary, but be prepared: the octopus gets eaten by a shark at the end. Octopuses die shortly after their eggs hatch. In this film, the octopus comes out of her den shortly after her eggs hatch and waits around for some other animal to eat her. By the time this happens in the documentary, you've become really attached to her, and it's heartbreaking. Still, it's worth watching. Her interaction with the filmmaker is really moving. There's scenes where she enthusiastically swims up to him, and he holds her against his chest and pets her while they cuddle. She is so curious and human like in all the best ways. But be prepared!
Also, there's a scene where a shark rips off one of her arms and she suffers for a week. It's really hard to watch.
In another scene, she chases down a crab and you see the crab panicking, swimming hard to get away, only to get eaten. The same for a lobster. It's not fun to watch these parts.
The struggle to breathe isn't shown, but the filmmaker notes several times where he is desperate to go up for air after being underwater for too long. There are shots of him gasping as he breaks the surface.
