The sun bear is the smallest bear species, native to tropical forests of Southeast Asia. It is named for the pale chest marking that resembles a rising sun.

What it is

The sun bear (*Helarctos malayanus*) is a small, short-haired bear with a dark coat and a distinctive pale or golden crescent-shaped mark on its chest. It is the smallest living bear species, adapted to warm, forested habitats, and is highly arboreal.

Key details

Sun bears are strong climbers, spending much of their time in trees. They are omnivores, eating insects, fruit, honey, leaves, and small vertebrates. They do not hibernate and can live up to 25 years in the wild. The species is listed as Vulnerable on the IUCN Red List.

Why it matters

Habitat loss and hunting are the main threats to sun bears. In Canada, they are relevant through zoo conservation programs and wildlife education, raising awareness about endangered species protection globally.
