Habitat and range
Where each species lives and the conditions it tolerates.
Sunda Clouded Leopard
tropical rainforest, montane forest
Lowland and hill dipterocarp forest, peat swamp forest and montane forest; the species also uses selectively logged forest, though at lower densities than in primary habitat.
Clouded Leopard
tropical rainforest, montane forest, dry forest
Primarily closed-canopy evergreen forest, but also recorded in secondary growth, mangrove, dry woodland and, in the Himalaya, forest above 8,000 feet.
Sunda Clouded Leopard
Asia
Endemic to Borneo and Sumatra, with separate subspecies recognised on each island.
Clouded Leopard
Asia
Mainland South East Asia and the eastern Himalaya: Nepal, north-east India, Bhutan, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia and southern China.
Diet and behaviour
Feeding ecology, social organisation and hunting technique.
Sunda Clouded Leopard
small mammals, primates, birds, medium ungulates
Bearded pig, mouse deer, macaques, proboscis monkeys, porcupines, civets and birds.
Clouded Leopard
primates, small mammals, birds, medium ungulates
Gibbons, macaques, slow lorises, porcupines, squirrels, pheasants, small deer and pigs, taken both in trees and on the ground.
Sunda Clouded Leopard
Solitary
Individuals maintain large home ranges relative to body size; detections are strongly associated with continuous forest cover.
Clouded Leopard
Solitary
Secretive and rarely observed directly; most ecological knowledge comes from camera trapping and a small number of radio-collared animals.
Sunda Clouded Leopard
Nocturnal and crepuscular
Camera-trap data show a strong night-time peak, with some crepuscular movement.
Clouded Leopard
Nocturnal and crepuscular
Camera-trap records cluster at night and around dusk, with daytime resting in trees.
Sunda Clouded Leopard
Stalking ambush in forest
Hunts both from branches and along the ground, taking prey up to the size of a young bearded pig.
Clouded Leopard
Arboreal and ground ambush
Prey is approached quietly and killed with a bite to the nape or skull, aided by unusually long canines.
Sunda Clouded Leopard
Exceptional
Highly arboreal, with the same rotating ankle anatomy as the mainland species.
Clouded Leopard
Exceptional
One of the most arboreal cats: it can hang from branches by its hind feet and climb down trunks head first.
Sunda Clouded Leopard
Capable
Recorded crossing rivers within its forest range.
Clouded Leopard
Capable
Recorded crossing rivers, though the species is not associated with wetlands.

Decreasing
Sunda Clouded Leopard
Conversion of forest to plantation, Logging, Fragmentation of lowland forest, Snaring, Trade in skins
Conversion of lowland forest to oil-palm plantation has removed a large share of the best habitat on both islands, leaving increasingly isolated forest blocks.
Clouded Leopard
Deforestation, Indiscriminate snaring, Trade in skins, teeth and bones, Prey depletion, Habitat fragmentation
Forest loss across South East Asia is the dominant pressure, compounded by intensive snaring that removes both the cat and its prey.
Notable traits
Details that do not fit neatly into a measurement table.
Sunda Clouded Leopard
- It was described as a distinct species only in 2006, after genetic comparison with mainland clouded leopards.
- Its cloud markings are smaller, darker-edged and more densely spotted than those of the mainland species.
- On Borneo it occupies the ecological role that tigers and leopards fill elsewhere in Asia.
Clouded Leopard
- Relative to skull length, its canines are the longest of any living cat, a proportion often compared with extinct sabre-toothed forms.
- Rotating hind ankles allow head-first descent, a trait shared with very few other cats.
- The tail can be as long as the head and body, acting as a balance beam in the canopy.
