Grizzled Tree Kangaroo

The grizzled tree-kangaroo grows to a length of about 75 to 90 cm (30 to 35 in) with males being considerably larger than females. It resembles a terrestrial kangaroo and its weight varies between about 8 and 15 kg (18 and 33 lb). The head is small, with a flat muzzle, the arms are powerful for climbing, the hind legs are long and the feet are large for an arboreal animal. The toes are armed with strong claws and the fourth toe is usually longer than the others. The otherwise bushy, cylindrical tail is often hairless at the base, and is used as a prop when climbing. Its colouring is between charcoal grey and chocolate brown with paler underparts. The ears are black and the toes and tail are dark.

The grizzled tree-kangaroo is native to tropical, foothill rainforests of northern and western New Guinea and some offshore island. It can be found at elevations up to 1,400 m (4,600 ft) above sea level. Its range includes the Foja Mountains and the Bird's Head Peninsula and it occurs on the offshore islands of Yapen, Waigeo, Misool and Salawati, and possibly Batanta. It is present in both primary and secondary forests.
