Sloth bears are not related to sloths. George Shaw, a European zoologist, believed they were related. He named this species for features they share with tree sloths such as their long, thick claws and teeth and the fact that sometimes they hang upside down on tree branches.

Sloth bears live in South Asia in the Indian Subcontinent covering the countries of Bangladesh, Bhutan, India, Nepal and Sri Lanka.
Its population is highly fragmented due to loss of habitat. It may be extinct in Bangladesh; the last documented records are from the late 1990s.
Their habitat consists of lowland tropical forest, grasslands, scrublands and savannas.

Sloth bears are covered in shaggy heavy black coat. The hair of its coat is long and measures from 80 to 200 mm. It is longer on the neck and shoulders.
Their snout is very long and cream colored.
They have a long tongue and a gap on their teeth that allows them to suck up ants, termites and bees. Their nostrils can close to protect themselves against insects.

The IUCN estimates that there are around 20,000 individuals in the wild with a decreasing population trend. There has been a 30 to 50% population decline over the past 30 years.
Habitat loss due to human settlement, development and industrialization.
Poaching and trade in sloth bear parts for traditional medicine.
Increasing number of encounters between humans and bears which lead to their death.

The IUCN Red List of Threatened Species lists the sloth bear as a vulnerable species.
According to the IUCN there are 174 Protected Areas in India.
Sloth bears are listed under Appendix 1 of CITES.
