The Babirusa! Photo # 1 of 2. This hairless, prehistoric-looking member of the pig family is found in Indonesia. Some scientists believe it may be more closely related to the Hippopotamus. Only males sport these impressive, wildly bizarre tusks. The ones protruding from the top of the snout are actually his upper canines, which grow UP rather than DOWN, penetrating through the skin, curling back towards the head, & in some cases, penetrating the skull a SECOND TIME!
