Sun bears are the smallest of all bear species, but have a reputation for being quite aggressive. Found in several countries in Southeast Asia like Cambodia, Indonesia and Vietnam, these bears have short black or dark brown water-repellent fur, with a yellow crescent on their chests.

Their strong paws are armed with long sharp, curved claws. They also possess the largest canine teeth of all the bear species considering their small size. While canines are meant for tearing meat, sun bears usually use their teeth for defence or for tearing the barks of trees to hunt for insects.

These bears are excellent climbers. They have flexible snouts and long tongues, which help them to dig up termites and raid beehives. The International Union for Conservation of Nature and Natural Resources (IUCN) classifies them as ‘data deficient’ as not much is known about these animals.
