tarsier (redirected from Tarsius)

tarsier (tär`sēər), small, nocturnal, forest-dwelling prosimian primate, genus Tarsius. There are at least three species found in the Philippines, in Sumatra and Borneo, and in Sulawesi. Tarsiers are about 6 in. (15 cm) long with a 10 in. (25 cm) hairless tail, and weigh about 4.5 oz (130 g). The body is covered with dense brown fur. Enormous round eyes are set close together in a flat face. Tarsiers' legs are specialized for climbing and jumping and end in long, thin digits bearing adhesive pads. They feed on insects and reptiles. They are believed to mate for life and to form family groups. Tarsiers are classified in the phylum Chordata, subphylum Vertebrata, class Mammalia, order Primates, family Tarsiidae.

tarsier

Any of three species (genus Tarsius, family Tarsiidae) of nocturnal prosimian primates found on several South Asian islands. Tarsiers have large, goggling eyes and a round head that can be rotated 180°. The ears are large, membranous, and almost constantly in motion. Tarsiers are 4–6 in. (9–16 cm) long; the thin, tufted tail of about twice that length provides balance and support. The gray to dark brown fur is thick and silky. Tarsiers cling vertically to trees and leap from trunk to trunk. They have greatly elongated hind limbs and disklike adhesive pads on the digit tips. Tarsiers prey mainly on insects. The well-furred newborn is born with eyes open.
