The Celebes warty pig (Sus celebensis), also called Sulawesi warty pig or Sulawesi pig, is a species in the pig genus (

domesticated and introduced to a number of other islands in Indonesia.[1]

Description

The Celebes warty pig is a medium-sized pig, and quite variable in size and appearance. Although a number of subspecies have been recognised, it is now regarded as a monotypic taxon. It is the only pig species that has been domesticated apart from the wild boar; being semi-domesticated may have had an influence on the variability of its appearance.[2] This pig has a head-and-body length of between 80 and 130 cm (30 and 50 in) and a long tail, with males generally being larger than females. The back is rounded and the legs short. The colour is greyish-black, sometimes tinged with red or yellow on the flanks. There are three pairs of facial warts and a fringe of pale bristles on the snout and more bristles on the cheeks. The crown and nape are topped by a short crest of dark bristles, while a dark mid-dorsal stripe extends from the crest towards the tufted tail.[3] Young pigs have longitudinal stripes, but these fade as the piglets grow.[2]

Distribution and habitat

The Celebes warty pig occurs in Sulawesi, being plentiful in central, eastern and south-eastern parts of the island but uncommon in the northeastern and southern parts.

Sus scrofa, and has become feral in some places, giving rise to a number of different pig populations.[1] It inhabits various habitat types including rainforest, swamp, cultivated land and grassland, at altitudes up to 2,500 m (8,000 ft).[1]

Ecology

This pig tends to move around in small groups of up to nine individuals, led by a dominant male and including several females and their offspring. Foraging takes place mainly in the early morning and the evening; the diet consists mainly of roots, shoots, leaves and fallen fruit, but also includes carrion, invertebrates and small vertebrates. Breeding takes place throughout the year. Gestation periods are probably between four and five months, and litter sizes can be up to eight, but in one study, averaged about two.[2] The most important natural predator is the reticulated python.[1]

Conservation status

The chief threats faced by this pig are an

loss of habitat has led the International Union for Conservation of Nature to assess the pig's conservation status as being "near threatened".[1]

Geology

At one point in time there may have been a portion of the land which shifted upward resulted in increased diversification. The researchers found out that the Sulawesi who roam the island today were preceded by other ancestors who once expanded from the innermost area of the island to the outermost part of it.
