Coloration is variable, ranging from black to smoky gray or creamy white on the upper parts and sooty gray, grayish white, or pure white on the underparts. White individuals and white-headed animals are common. The long tail is prehensile and evenly furred, except for the naked underpart of the tip.
Females have a well-developed pouch and two mammae.
This attractive marsupial has been reported to glide for up to 78 meters. Apparently this possum travels across open ground at times, but it spends nearly its entire life in trees. It is nocturnal, sheltering by day in hollows high up in trees. Some individuals make a nest of stripped bark or leaves in their den, but often no material is added. There is some indication that this possum transports nesting material in its rolled-up tail.
