I would like to strongly recommend the following film to anyone who has access to Netflix. It’s called My Octopus Teacher and is an amazing documentary about a diver and photographer in South Africa who forms a relationship with a wild common octopus. It was filmed over the period of a year in a cold underwater kelp forest at a remote location in False Bay, near Cape Town.
The photography is stunning and it gives a wonderful insight into the life of the octopus and the effect it has on the man himself. Very moving and beautiful!
