Fossa

The fossa (Cryptoprocta ferox) is Madagascar's largest native carnivore, a cat-like mammal belonging to the family Eupleridae, which evolved in near-total isolation from the African mainland. Reaching up to 80 centimeters in body length with a tail of nearly equal length, it is built for agility in forest habitats, with semi-retractable claws and flexible ankles that allow it to descend trees headfirst. It is the apex predator of Madagascar's forests, and the only predator capable of taking adult lemurs across most of the island's range.

The fossa is listed as Vulnerable on the IUCN Red List, with a population that has declined significantly as Madagascar has lost more than 90 percent of its original forest cover, according to WWF estimates. Habitat destruction driven by slash-and-burn agriculture, charcoal production, and logging has fragmented the remaining forest into isolated patches. Persecution by local communities, who sometimes kill fossa in retaliation for predation on domestic poultry and livestock, adds additional pressure. Because the species has a naturally low reproductive rate and requires large territories, local populations struggle to recover once they are reduced.
