Dicerorhinus sumatrensis (Sumatran rhinoceros)
Synonyms: Rhinoceros crossii
The Sumatran rhinoceros (Dicerorhinus sumatrensis) is a member of the family Rhinocerotidae and one of five extant rhinoceroses. It is the only extant species of the genus Dicerorhinus. It is the smallest rhinoceros, although is still a large mammal. This rhino stands 112–145 cm ( ) high at the shoulder, with a head-and-body length of 2.36–3.18 m ( ) and a tail of 35–70 cm ( ).
This two-horned rhino is the smallest and most threatened of the five living rhinoceros species. It is sometimes referred to as the hairy rhino because of the long coarse hair that covers its body. The species leads a solitary life deep in the rainforests of South East Asia, where it has survived virtually unchanged for a million years. Sadly, human activities have brought the species to brink of extinction. Extensive deforestation and poaching for the horn have caused a dramatic decline in rhino numbers, and it is estimated that fewer than 275 individuals survive today in very small and highly fragmented populations.
