Overview
The sun bear (Helarctos malayanus), also called the honey bear, is the smallest extant bear species native to Southeast Asia. Its common name refers to the crescent- or patch-shaped pale marking on the chest, which can resemble a rising sun. Taxonomically it has been placed in the genus Helarctos, though older sources sometimes list it under Ursus. Sun bears inhabit tropical forests across the Malay Peninsula, Borneo, Sumatra and parts of mainland Indochina.
Physical characteristics
Sun bears are compact, short-haired bears with distinctive features adapted to an arboreal, insect-rich diet. Key traits include:
- Size: The smallest of the bears, with a short, sleek black coat.
- Chest mark: A crescent or patch of pale fur on the chest that varies between individuals.
- Claws and tongue: Long, curved front claws for climbing and tearing; a long, protrusible tongue useful for extracting insects and honey.
Habitat and behaviour
Sun bears are primarily forest dwellers, using both lowland and montane tropical forests. They are excellent climbers and spend a great deal of time in trees, where they forage, rest, and build temporary nests. Activity patterns vary locally; sun bears can be more nocturnal in areas with human disturbance. They are generally solitary except for females with cubs.
Diet and ecological role
These bears are omnivorous: fruit and berries make up an important portion of their diet, supplemented by insects (notably termites and ants), honey, and small vertebrates. By consuming fruit and dispersing seeds, sun bears contribute to forest regeneration; by preying on insect colonies they help control invertebrate populations.
Conservation and threats
The sun bear is classified as Vulnerable due to rapid habitat loss and direct exploitation. Major threats include the clearance of forests for agriculture (especially oil palm), logging, hunting for meat and body parts, and capture for the illegal pet or bile trade. Conservation efforts focus on habitat protection, anti-poaching measures, and community engagement.

Notable facts and distinctions
Unlike larger temperate bears, sun bears are closely associated with tropical trees and often make use of standing trunks to access food. They are sometimes called "honey bears" because of their habit of raiding bee nests, and their long tongues are a characteristic adaptation to this feeding style.
