Cryptoprocta ferox, commonly known as the fossa, is a carnivorous mammal endemic to Madagascar. It resembles a small cougar, with a slender body, muscular limbs, and retractable claws. It is the island's top predator, primarily hunting lemurs. Fossas are solitary and arboreal, with a keen sense of smell and excellent climbing abilities.

Cryptoprocta ferox, commonly known as the fossa, is native to Madagascar. This island nation, located off the southeastern coast of Africa, is the only place in the world where the fossa naturally occurs.

The fossa inhabits a variety of forest types within Madagascar, including rainforests, dry deciduous forests, and spiny forests. These environments provide dense cover and a rich diversity of prey, which are crucial for the fossa's survival. The climate in these areas can vary but is generally characterized by distinct wet and dry seasons. In the rainforests, the climate is humid and warm year-round, while the dry forests experience more pronounced seasonal changes with dry, cooler periods.

The fossa is a top predator in its habitat, playing a crucial role in controlling the populations of other species, particularly lemurs, which constitute a significant part of its diet. Its ecological niche involves being a solitary and elusive carnivore, well-adapted to climbing and hunting in the trees, as well as on the ground. The fossa's ability to traverse different forest types highlights its adaptability to various environmental conditions within its native region.
