Loris, a small, tree-dwelling primate inhabiting the forests of southeastern Asia and Indonesia. Lorises are closely related to galagos and pottos.
Lorises have large eyes; small, rounded ears; and long, slender limbs. They are either tailless or have stubby tails. Their thick, fluffy fur is gray or brown above and light gray below. There is a mask on the face. Lorises live in trees and use their sharp claws and strong hands and feet for climbing and grasping. Lorises sleep during the day and feed at night on fruit, insects, and small reptiles and birds. Lorises generally move slowly but can move quickly if threatened.
There are three species—the slender loris, the slow loris, and the pygmy loris. The slender loris is 7 to 9 inches (17 to 23 cm) long; the slow loris, 12 to 15 inches (30 to 38 cm); and the pygmy loris, 7 to 8 inches (17 to 20 cm). The pygmy loris is threatened with extinction because of loss of its habitat.
Lorises belong to the family Lorisidae. The slender loris is Loris tardigradus; the slow loris, Nycticebus cougang; the pygmy loris, N. pygmaeus.
