Sloth bears are considered mymecophagists or "termite and ant eaters". They have special feeding modifications that allow them to be expert termite consumers. They use their long, curved claws to dig into deteriorating logs, blow the dust away and then suck up termites like a vacuum cleaner. They have a hollow palate and have no upper incisors to allow for easy consumption of the insects. They can voluntarily close off their nostrils and their nose has no hair. This insures that they will not get the sticky substance that termites release stuck in their hair or in their nose. The termite eating noise from this process can be heard from 200 yards (180m) away.

Sloth bears are omnivorous. In the wild, their diet is primarily insects and seasonal fruit. At the Zoo, the bears are offered a base diet of commercial omnivore bear biscuit and a gruel mixture of dog meal, peanut butter, honey and apple juice. The gruel mixture allows them to use their unique lip and teeth adaptation. This enables the bear to form their very pliable lips into a tube. The bears also lack upper incisors thus they are able to suck up the gruel as through a straw. In addition to the base diet, a variety of enrichment foods are offered, including fruit, insects and cheerios.
India, Nepal, Sri Lanka, Bhutan. They range through dry or wet tropical forests, savannas, scrublands and grasslands and will utilize shallow caves as denning sites.
On the 2011 IUCN Red List of Threatened Species, the sloth bear is listed as Vulnerable.
