Clouded leopard

The clouded leopard ("Neofelis nebulosa") is a rare cat species. It is a medium-sized felid, found from the Himalayan foothills through mainland Southeast Asia into China. It is 55 to 110 cm (2 ft to 3 ft 6 in) long and weighs between 15 and 23 kg (33 to 50 lb). It is classified as vulnerable in 2008 by IUCN. Its total population may be fewer than 10,000 mature individuals.
Clouded leopards hunt in trees as well as on the ground. Their prey are monkeys and birds. They are one of the few cats who are arboreal.
The genetic analysis of specimens of "Neofelis nebulosa" and its close relative "Neofelis diardi" suggests the two species diverged 1.4 million years ago. A group crossed a now submerged land bridge to Borneo and Sumatra from mainland Asia. And, the Sunda clouded leopard is different enough on the two large islands to be classed as two subspecies.
The split between the two subspecies corresponds roughly with the catastrophic eruption of the Toba supervolcano in Sumatra 69,000–77,000 years ago. A probable scenario is that Sunda clouded leopards from Borneo recolonized Sumatra during periods of low sea levels in the Pleistocene, and these were later separated from their source population by rising sea levels.
