Goodfellow's tree kangaroo  (Dendrolagus goodfellowi)

Like other tree kangaroos, Goodfellow's tree kangaroo differs noticeably from the better-known ground kangaroos because it has developed specialised adaptations to its arboreal lifestyle (2). These include shorter hind limbs, strong, stocky arms, and a long tail for balance while leaping among the branches (2) (3). The feet are also broader than those of ground kangaroos, and have padded soles to aid with gripping and sharp curved claws for climbing (2) (3). This slender-bodied tree kangaroo has short, usually woolly fur that ranges from chestnut-brown to crimson (3), with a paler underside, grey-brown face and yellow neck, cheeks and feet (2). A characteristic pair of golden stripes runs down the centre of the back and each individual has a unique pattern of yellow rings and blotches on the tail (4). Males are slightly larger than females (5).
