Generally S. verrucosus appears somewhat reddish, but some individuals look quite black from a distance. The hair on the crown and the mane on the back of the neck are usually paler, often reddish-orange and occasionally approaching blond. In S. verrucosus of all sexes and ages the hair on the belly is predominantly white or yellowish, contrasting with the darker pelage on the upper part of the body. S.

. The reasons for this are not known, but it might be because the pigs are unable to tolerate low temperatures. They evidently prefer secondary or disturbed forests, though they are also often found near the coasts in remnant patches of mangrove and swamp forest. They are rare in the few remaining lowland primary forests and in areas with high human populations where otherwise suitable habitat is fragmented and surrounded by agricultural land. However, they do feed on crops, making nocturnal raids on fields of corn and cassava. As with S.

The gestation period is thought to be about four months, and 3-9 young are born. Most births reportedly occur in the rainy season, from January to March, in a large nest made by the female out ofleaflitter. According to a recent informant, females with young are mostly seen between August and December.

It could be that a shift from generally diurnal activity patterns in pigs to nocturnal ones is because of the very high hunting pressure on the species.

. Several interviewees reported recent sightings of S. verrucosus from the area around Cilacap, Cipatujuh, and Nusa Kembangan, including some from the Nusa Kembangan Nature Reserve off Cilacap, but the species seems to be rare and fragmented into small populations. The only areas where S. verrucosus reportedly remained common were around Subah, where animals were generally seen in small groups of 1-2 individuals and groups of 4-6 during the mating season, and around Blora and Bojonegoro. In the latter area, group size had reportedly declined from 10-20 to only 1-3. No recent records of S. verrucosus exist from Madura Island, and the species is considered extirpated there. On Bawean Island, the only area where the subspecies blouchi occurs, the species is now very rare, and possibly already extirpated. There are no estimates of overall population size, but the species has shown a rapid population decline in recent decades. Compared to a survey conducted in 1982, 17 of the 32 populations (53%) are extirpated or have dropped to low encounter rate levels. [tis thought that the population decline observed in this species is primarily caused by a decline in suitable habitat, especially of stands of teak forest or similar forest plantations, and by high hunting pressure. These animals are killed both by sport hunters and by farmers protecting their crops. Many animals are killed by poisoning. As yet unpublished reports of the recent dramatic reduction in numbers, possibly resulting in the extirpation of subspecies blouchi on Bawean Island have been attributed to correspondingly increased hunting pressure following the recent settlement of Christian immigrants from
