The hippos that traded freshwater rivers for the open sea

The Island of the Hippos | Where Hippos Meet the Sea · 50:50 · Video: Beautiful World - Documentaries · Watch at the source

In short: Most hippos are bound to inland rivers, but a unique colony in Guinea-Bissau has mastered a different frontier. This documentary explores how these mammals adapted to life in the salt and brine of the Bijagós Archipelago.

Located in West Africa, the Bijagós Archipelago is home to the westernmost population of hippos. These animals have adapted to thrive in brackish, saline environments rather than traditional freshwater habitats. The film examines their specific social structures and territorial behaviors within this coastal niche.

The documentary highlights a critical survival strategy: females often move into the coastal waters to give birth, seeking safer conditions for their young. By observing these movements into the sea, the film provides a rare look at how this species interacts with a unique, biodiverse ecosystem.
