For a long time, sloth bears were confused with another tropical animal called a sloth. These shaggy, docile bears have a unique appearance and some interesting adaptations. Unlike their North American relatives, sloth bears live together in groups where the male is part of the cubs’ upbringing.
Sloth Bear
Habitat
- Sloth bears live in warm, humid forests or in grasslands near the equator.
- They can live in a wide variety of forest types from dry thorn forests in the north to wet tropical forests in the south.
Distribution
- Sloth bears live in Southeast Asia primarily in the forest areas of Sri Lanka and India.
- They have also been reported in Bangladesh, Nepal, and Burma.
- Their populations are estimated to be between 1000 and 7000.
Physical Characteristics
Color
- Sloth bears have long, shaggy black fur with a large white or yellow Y-shaped patch of hair on their chests.
- They have particularly long hair around their necks, which looks like a mane. They have little fur on their bellies and the insides of their legs.
Size
- Adult sloth bears usually weigh about 300 pounds, females being somewhat smaller than the males.
- They are usually 3 feet high at the shoulder and about 6 feet long.
Features
- Sloth bears have a long muzzle with lips that can be closed.
- They have a hollowed-out bony palate and no front teeth so they can suck ants and termites out of their nests. People can sometimes actually hear the bear sucking up insects from 300 feet away.
- They have white curved, blunt claws that are up to 3 inches (7 cm) long.
- Their tails are approximately 6 inches (15 cm) long.
Diet
- Sloth bears eat a wide variety of different plants, animals, and insects but prefer termites.
- They will eat fruit, raid beehives for honey, scavenge from tiger kills, or eat cultivated crops such as sugarcane, corn, and yams.
Behavior
Daily Activity
- They are mostly nocturnal, feeding and traveling by night and sleeping in the day.
- They are excellent tree climbers and are often seen hanging from a tree limb like a sloth.
- Unlike other bear species, they seem to enjoy the company of other sloth bears.
Hibernation
- Sloth bears do not hibernate.
- During monsoon season they may head for caves or other retreats where they become lethargic and wait out the rains.
Reproduction
- Sloth bears mate year-round.
- Most cubs are born in December or January in a nest that the mother builds in a cave or under some rocks.
- Usually two or three cubs are born to a mother. They are born blind and helpless.
- By one month sloth bear cubs are able to travel through the forest with their parents.
- The cubs sometimes ride on their mothers’ back by holding onto her shaggy coat.
- They stay with their mothers for 2 to 3 years or until they reach approximately 50 pounds (22 kg), when they begin to travel on their own.
People and Sloth Bears
Historically:
- Due to increasing human population and encroachment for housing and farming, sloth bears and their habitat are disappearing.
- Logging and other resource extraction are also having serious impacts.
- Sloth bears live in a part of the world where people are struggling to make a living, so wildlife conservation is not considered to be a top priority.
- Fortunately, in India conservation efforts to save the Bengal tiger have also helped to conserve sloth bears and their habitat.
