The Fosa is Madagascar’s largest predator – apart from the crocodile. It is a civet-like animal but it differs considerably from the African civets. An adult Fosa measures about two metres, the tail included. Like real cats the Fosa can draw its claws and is thus an expert climber. It feeds on lemurs. It is hard to spot the fosa as it is nocturnal and secretive. It should not be confused with the fanalouc and the falanoka, other predators, a bit smaller than the fosa. All three named foosa by the local population.
