Sloth bear

Melursus ursinus

Also calledBhālū (Hindi) · Rīch (Hindi/Urdu) · Karadi (Tamil/Kannada) · Valaha (Sinhala)

A shaggy, termite-eating bear of India and Sri Lanka that vacuums insects out of their mounds. It lacks upper front incisors, can close its nostrils, and uses its protrusible lips like a suction tube. Despite its insect diet it is one of the most dangerous animals in India, attacking when surprised at close range.

The sloth bear, also known as the Indian bear, is a myrmecophagous bear species native to the Indian subcontinent. It feeds on fruits, ants and termites. It is listed as vulnerable on the IUCN Red List, mainly because of habitat loss and degradation. It is the only species in the genus Melursus. Wikipedia

In the field

Field marks

  • aShaggy, unkempt black coat, longest on the shoulders and neck
  • bPale, mobile muzzle with a long lower lip
  • cWhite or yellowish U- or Y-shaped chest mark
  • dSigns: termite mounds torn open with scattered soil; tracks show long claw marks well ahead of the toes; scats packed with termite remains
Not to be confused with
Asiatic black bear has a neat short coat, a V-shaped crescent on the chest, round ears and lives mainly in the Himalaya and northeast. Wild boar from a distance is smaller-headed with a bristly crest.

Largely nocturnal where disturbed. Does not hibernate. Charges when startled, a defensive reaction that accounts for many human injuries.

Marginalia

For centuries the Kalandar community trained sloth bears as 'dancing bears'; through a rehabilitation programme led by Wildlife SOS and partners, the practice ended in India around 2009. Kipling's Baloo in The Jungle Book is a sloth bear.

Curiosity

European naturalists first classified it as a kind of sloth, naming it Bradypus ursinus in 1791 on the strength of its long curved claws and missing upper incisors; the name 'sloth bear' stuck.
