Shaggy, dusty, and unkempt, the reclusive sloth bear makes its home in the forests of South Asia. Emitting noisy grunts and snorts, it wanders alone, usually at night, in search of insects and fresh fruit.

Feeding Behavior

Sloth bears feed predominantly on termites and ants and employ a well-evolved method to dig them out. Their long, curved claws are used for penetrating nest mounds, which can be rock-hard. Once they’ve opened a hole, they blow away excess dirt then noisily suck out the insects through a gap in their front teeth. To do so, they close their nostrils and use their lips like a vacuum nozzle.

Beyond insects, sloth bears feast on a variety of fruit and flowers, including mango, fig, and ebony. They are also known to scale the occasional tree to knock down a bee honeycomb, which they will then enjoy on the ground below. It is this habit that’s given rise to their nickname, honey bears.

Size and Appearance

Sloth bears are solitary creatures and generally nocturnal. They grow up to 6 feet in length, and males can weigh up to 310 pounds, while females weigh up to 210 pounds. When threatened they respond by standing on their hind legs and displaying their formidable foreclaws.

They wear an extremely shaggy black coat and a cream-colored snout, and their chest is usually marked with a whitish “V” or “Y” design.

Reproduction

After a six- to seven-month gestation period sloth bears normally give birth to a litter of two cubs in an underground den. The cubs will often ride on their mother’s back, a unique trait among bears.
