# Sun Bear (*Helarctos malayanus*)

> The sun bear is the smallest bear species, weighing 25–65 kg (55–145 lb) with a distinctive golden chest patch and long tongue for reaching honey and insects. Found in tropical forests of Southeast Asia, it is listed Vulnerable due to deforestation and the illegal pet and bile trade.

## Chest patch and tree life

The sun bear's U- or crescent-shaped chest mark varies from pale yellow to orange and may help with individual recognition. Unlike larger bears, sun bears spend much of their time in trees, using long curved claws and bare-soled feet to climb in search of fruit, honey, and insects.

## Diet and the honey bear

Sun bears are opportunistic omnivores with an exceptionally long tongue — up to 25 cm — used to extract honey, termites, and beetle larvae from nests. Fig trees and oil-palm fruit draw them to forest edges, where conflict with plantations and poaching increase.

## Solitary habits and reproduction

Adults are largely solitary outside the breeding season. Females typically produce one or two cubs after a gestation of about three months. Cubs stay with the mother for up to three years, learning to climb and forage in dense canopy.

## Conservation threats

Listed Vulnerable, sun bears face rapid habitat loss from logging and palm-oil expansion, plus poaching for gall bladders, paws, and the pet trade. Cubs are often taken after mothers are killed. Protected areas and anti-poaching patrols are critical across Malaysia, Indonesia, and Thailand.

### Where do sun bears live?

Tropical rainforests of Southeast Asia, including Borneo, Sumatra, peninsular Malaysia, Thailand, Myanmar, Laos, Cambodia, and Vietnam.

### Are sun bears endangered?

They are listed Vulnerable on the IUCN Red List, with populations declining from habitat loss and illegal trade rather than natural causes.
