Habitat
Fossas primarily inhabit the forests of Madagascar, including both humid rainforests and dry deciduous forests. They prefer areas with dense vegetation for hunting and shelter, often found in mountainous regions up to 2,000 meters elevation. They are adaptable but rely on tree cover to avoid open areas.
Diet
Fossas are carnivorous predators that mainly feed on lemurs, such as the ring-tailed lemur and mouse lemurs, which they hunt by ambushing from trees or the ground. They also consume rodents, birds, reptiles like chameleons, and occasionally fruits or insects. Feeding occurs primarily at night, with fossas using their agility to chase and capture prey.
Behavior
Fossas are solitary animals that are primarily nocturnal, resting in trees or dens during the day and becoming active at night to hunt. They are highly territorial, marking their ranges with scent glands and defending them aggressively against intruders. Notable behaviors include excellent climbing and swimming abilities, which they use to pursue prey, and vocalizations like screams during mating season.
Conservation Status
The fossa is classified as Vulnerable by the IUCN due to habitat loss from deforestation and hunting. Population trends are decreasing, with major threats including fragmentation of forests and the illegal pet trade.
