Fossa
Cryptoprocta ferox
Fossa are the largest carnivores in Madagascar.
Little is known about fossa because they are elusive, solitary and have nocturnal habits.
Their resemblance to cats suggests a connection to the cat family but they are also closely related to civets and mongooses.
Unlike cats, fossa walk on the soles of their feet rather than on their toes.
Their eyes are also peculiar – brown and opaque, their pupils often reduce to the size of pinpricks.
Diet
Fossa eat lemurs, other small mammals, birds and fish.
Size
The average fossa can measure up to 80 centimetres (cm). Their tails can be up to 70cm long and they can weigh up to 12 kilograms.
Location
Fossa are only found in the tropical forests of Madagascar.
