Cubs are born in an underground den, and stay there for several months. After emerging from the den, cubs stay at their mother's side for two to three years before heading off on their own. But these bears have lived up to 40 years in zoos. Active mostly at night, the sloth bear is a noisy, busy bear. It grunts and snorts as it pulls down branches to get fruit, digs for termites, or snuffles under debris for grubs and beetles.
Sloth bears lead solitary lives, and most are nocturnal.
If threatened, these smallish bears will stand on two legs, brandishing their clawed forepaws as weapons. At the top of the forest food chain, this mighty, endangered cat slinks through the shadows in search of spotted deer and other prey, which sometimes includes sloth bears. A massive, forest-dwelling wild ox that lives in small herds and feeds in clearings at night. An endangered, black-coated monkey with a distinctive gray mane and dangling tail. Troops of 12 to 20 inhabit tropical evergreen forests in India's Western Ghats mountains.
