The Striped Possum (Dactylopsila trivirgata) is a member of the Petauridae family,[3] one of the marsupial families. The species is black with three white stripes running head to tail, and its head has white stripes that form a 'Y' shape. It is closely related to the Sugar Glider, and is similar in appearance.


Range

The Striped Possum lives in rainforests and eucalypt woodland along the east coast of Cape York Peninsula and as far south as Townsville in Queensland, Australia, but is more commonly found in New Guinea.[3] as well as several other small islands in the area. Uncommon and rarely seen in Australia.[4]

Description

This possum looks like a black and white squirrel. It is solitary, mostly nocturnal, arboreal, and builds nests in tree branches.[5] The body length is approx. 263 mm long, tail 325 mm, and weight 423 g.[6] The Striped Possum's tail is prehensile.[3] Its fourth finger is elongated relative to the others (like the third finger of the Aye-aye, another rainforest mammal) and is used to take beetles and caterpillars from tree bark,[7] making it a "mammalian woodpecker".[8] In addition, the Striped Possum eats leaves, fruits, and small vertebrates.[3] Its main diet consists of wood-boring insect larvae which are extracted from rotten branches probing with its elongated fourth finger and its powerful incisor teeth which are used to rip open tree bark to expose insects. It detects the larvae by a rapid drumming along branches with the toes of its forefoot.[9] The fourth finger has an unusual hooked nail which it uses to extract insects out of cracks.[10]

It emits a "very powerful unpleasant smell."[11] It is noisy and growls. During the day it curls up on an exposed branch and sleeps.[12]

The female striped possum has two teats in her pouch and can give birth to as many as two young.[3] However, not a lot is known of this possum's breeding habits.

It is most easily found by the sound it makes chewing and drinking in the forest. The Striped Possum is one of the least known marsupials. The species is not considered to be threatened.
