Fossa: The Mysterious Madagascan ‘Mongoose’
The fossa is Madagascar’s top dog. Not that it’s actually a dog, of course, because Madagascar doesn’t have any wild dogs. Nor does it have any wild cats, bears, badgers, weasels or raccoons. In their absence, the top predator on the island is an elusive, medium-sized brown animal that looks a bit like a cross between an elongated puma and a giant otter.
