It has two pairs of large tusks composed of enlarged canine teeth. The upper canines penetrate the top of the snout, curving back toward the forehead. The North Sulawesi babirusa is threatened from hunting and deforestation. The common and scientific names are various transcriptions of its local name, which literally translated means "pig-deer" (from Indonesian "babi", "pig" + "rusa", "deer" – see also Javan rusa) in reference to the huge tusks of the male
Babirusa a babirusa are capable of easily cracking hard nuts. Male babirusa tend to live solitarily while adult females can be found in groups with young. Groups of female and young babirusa may number up to 84 individuals, most of which contain no adult males. Males rarely travel in pairs or trios. The tusks of the adult males are used in intraspecific fighting. The upper tusks are for defense while the lower tusks are offensive weapons. If a babirusa does not grind its tusks (achievable through regular activity), they can eventually keep growing so as to penetrate the animal's own skull.
