Sun Bear

Although the sun bear is the smallest of all bears, it is also one of the most aggressive, and is equipped with particularly fearsome canine teeth. The world’s smallest bear rarely stands taller than 1.5 m (5 ft) and has a short coat.

Living in lowland areas of tropical rainforest, sun bears are solitary by nature and nocturnal in their habits. They can climb well — aided by their relatively small size and the way in which their paws curve inwards - and will even rest off the ground during the day. Relatively little is known about their habits, although they tend to find their food by their sense of smell as their eyesight is poor. They can occasionally cause havoc on cacao and coconut plantations.

The Sun Bear has curved claws for climbing trees and an elongated tongue for eating insects which it finds in the canopy. It will also eat rodents, lizards, honey and the soft insides of palm trees. In more urban areas, it has been seen eating banana crops and refuse. In common with most bears, it is hunted for its medicinal value according to local beliefs, and a combination of hunting and habitat destruction has led to a serious decline in populations of bears, with possibly only a few thousand left.
