The babirusa is a rare wild pig that lives in Southeast Asia. Their most distinctive characteristic is their unusual tusks. Unlike other pig species, the upper pair of tusks on the male babirusa will grow up through its snout. These upper tusks can grow to be about 10 in. (25cm) long and will curve back towards the animal’s eyes but are not sharp. The lower pair also grows upward from the corners of its mouth, but these lower tusks are sharp. These features make the babirusa an unusual looking animal.
