You may recognize the Great African Seaforest from television. The lush kelp forest was showcased in the 2020 Netflix documentary My Octopus Teacher, which follows a diver as he develops a unique bond with an octopus who welcomes him into her underwater world.

The Great African Seaforest is the only forest of giant bamboo kelp in the world. It extends from the shores of Cape Town to Namibia (a distance of more than 600 miles) and is the site of the discovery of the oldest archaeological evidence of art and science.5

This stunning underwater forest is rich in marine life, home to about 14,000 different plant and animal species.6 In addition to the cuttlefish, octopuses, and colorful starfish that live among the long, brown kelp strands, sharks endemic to South Africa frequent the area to lay eggs.
