Babyrousa, commonly known as babirusas, are notable for their distinctive curved tusks, which can grow through the skin of their snouts. These wild pigs inhabit the rainforests of Indonesia's Sulawesi and nearby islands, where they forage for fruits, leaves, and small invertebrates. Babirusas are solitary or live in small groups and play a crucial role in seed dispersal within their ecosystem.

The genus Babyrousa, commonly known as babirusas, is native to the Indonesian islands. These islands include Sulawesi, Togian, Sula, and Buru. Each island hosts distinct species or subspecies of babirusa, reflecting their unique geographical distribution.

Babirusas inhabit tropical rainforests, swamps, and riverine forests. These environments are characterized by high humidity, dense vegetation, and a warm climate typical of equatorial regions. The areas are often near rivers or other water sources, providing ample opportunities for wallowing, which is a common behavior among babirusas.

Babirusas are primarily herbivorous and play a role as browsers in their ecosystem. They feed on leaves, fruits, berries, and occasionally small animals. Their presence contributes to seed dispersal and the maintenance of plant diversity in their habitats. Babirusas have adapted to their environment with elongated limbs and a relatively hairless body, which helps them move through dense forest undergrowth and maintain body temperature in the humid conditions.
