Sulawesi Babirusa (Babyrousa celebensis)
Family: Pig Family (Suidae)
IUCN Conservation Status: Vulnerable
Native to the islands of Sulawesi, Pulau Muna, Butung and Lembeh in Indonesia, the Sulawesi Babirusa is a small, slender, almost entirely hairless species of wild pig best known for the four enormous curled tusks seen in adult males (which are derived from highly elongated canine teeth,) although adult females also possess a single pair of smaller, less elaborate tusks protruding from their lower jaws. The tusks of a male babirusa are used to intimidate rival males and impress potential mates (with females generally preferring males with larger, curlier tusks,) although despite their impressive appearance they are brittle and unsuited for fighting; males generally resolve conflicts through intimidation alone, but if a fight does occur they instead rear up onto their hind legs and strike at each other with their front hooves, similar to a clumsier version of the boxing behaviour of hares. Typically inhabiting dense forests or canebrakes (forest-like areas dominated by tall bamboo of the genus Arundinaria,) members of this species tend to remain near permanent bodies of water such as rivers and large ponds and feed mainly on fallen fruit, although like other pig species they are unspecialised omnivores and will also readily consume leaves, roots and small invertebrates. Female Sulawesi Babirusas live in groups of around 15 adults accompanied by their young, while males are generally solitary outside of the mating season (between January and August). Unlike most pigs females of this species produce only small litters of 1-2 piglets each year, with young being born tuskless and covered in a coat of short, reddish-brown hair.
