About Presbytis thomasi (Collett, 1893)
This species, known as Thomas's langur with the scientific name Presbytis thomasi (Collett, 1893), has distinct physical features. The hair on the top of its head stands up in a crown-like formation that resembles a mohawk. The front of this head crown is white, with a dark grey stripe running down its center. Two separate tufts of fur extend outward from either side of the animal's face. Its belly is cream-colored, while its back is grey. It has amber-colored eyes, with grey fur outlining the area around each eye. Juvenile Thomas's langurs have creamy white fur. In its ecosystem, Thomas's langur is preyed on by clouded leopards, Sumatran tigers, bay cats, and reticulated pythons. These predators are especially dangerous to the species when Thomas's langur is on the ground. Thomas's langur provides two ecological services: it disperses the seeds of the plants it eats, and it pollinates the flowers of these consumed plants.
