A natural paradise located off the coast of Guinea Bissau, the Bissagos archipelago is a strategic place for the conservation of the planet's biodiversity. Only 23 of its 88 islands are inhabited by a population very respectful of its environment. They are an ideal refuge for a rich wildlife. Among them, we find the only hippos in the world that live part of their time in sea water, as well as crocodiles, manatees, sand fiddler crabs and periophthalmus, strange fish with frog-like eyes.
