About the Greater Mouse-deer

The greater mouse-deer, greater Malay chevrotain, or napu (Tragulus napu) is a species of even-toed ungulate in the family Tragulidae found in Sumatra, Borneo, and smaller Malaysian and Indonesian islands, and in southern Myanmar, southern Thailand, and peninsular Malaysia. Its natural habitat is subtropical or tropical, moist, lowland forest.

Tragos is Greek for "goat" and –ulus in Latin means "tiny". Napu is a local name, from Malay napuh. The name "mouse-deer" refers to its small size and does not imply that it is a true deer. It is called "greater" because it is larger than other Tragulus species.

The greater mouse-deer is an even-toed ungulate. Although very small for an ungulate, the greater mouse-deer is one of the largest members of its genus. It is rivalled in size by Williamson's mouse-deer. It weighs 5 to 8 kg (11 to 18 lb). Its head-and-body length is 70 to 75 cm (2.30 to 2.46 ft) and its tail length is 8 to 10 cm (3.1 to 3.9 in). Its shoulder height is about 30 to 35 cm (12 to 14 in) It has a small, triangular head with a small, pointed, black nose and large eyes. Its long legs are as thin as a pencil. The hind legs are visibly longer... Wikipedia →
