Sloth bears breed during spring and early summer and give birth near the beginning of winter. When their territories are encroached upon by humans, they sometimes attack them. Historically, humans have drastically reduced these bears' habitat and diminished their population by hunting them for food and products such as their bacula and claws. Sloth bears have been tamed and used as performing animals and as pets.
Taxonomy
George Shaw in 1791 named the species ''Bradypus ursinus''. In 1793, Meyer named it ''Melursus lybius'', and in 1817, de Blainville named it ''Ursus labiatus'' because of its long lips. Illiger named it ''Prochilus hirsutus'', the Greek genus name indicating long lips, while the specific name noted its long and coarse hair. Fischer called it ''Chondrorhynchus hirsutus'', while Tiedemann named it ''Ursus longirostris''.

Sloth bear muzzles are thick and long, with small jaws and bulbous snouts with wide nostrils. They have long lower lips which can be stretched over the outer edge of their noses, and they lack upper incisors, thus allowing them to suck up large numbers of insects. The premolars and molars are smaller than in other bears, as they do not chew as much vegetation. In adults, the teeth are usually in poor condition, due to the amount of soil they suck up and chew when feeding on insects. The back of the

, "Bear Behavior and Activities" Although they appear slow and clumsy, both young and adult sloth bears are excellent climbers. They occasionally will climb to feed and to rest, though not to escape enemies, as they prefer to stand their ground. Sloth bear mothers carry their cubs up trees as the primary defense against attacks by predators instead of sending them up trees. The cubs can be threatened by predators such as tigers, leopards, and other bears. They are adequate climbers on more accessible trees but cannot climb as quickly or on as varied surfaces as can black bears due to the sloth species' more elongated claw structure. Given their smaller size and still shorter claws, sloth bear cubs probably climb more proficiently than adults (much as brown bear cubs can climb well but not adults). They are good swimmers, and primarily enter water to play.
To mark their territories, sloth bears scrape trees with their forepaws, and rub against them with their flanks. Sloth bears are recorded to produce several sounds and vocals. Howls, squeals, screams, barks and trumpet-like calls are made during aggressive encounters while huffing is made as a warning signal. Chuffing calls are made when disturbed. Females keep in contact with their cubs with a grunt-whicker while cubs yelp when separated.
Reproduction
The breeding season for sloth bears varies according to location: in India, they mate in April, May, and June, and give birth in December and early January, while in Sri Lanka, it occurs all year. Sows gestate for 210 days, and typically give birth in caves or in shelters under boulders. Litters usually consist of one or two cubs, or rarely three. Cubs are born blind, and open their eyes after four weeks. Sloth bear cubs develop quickly compared to most other bear species: they start walking a month after birth, become independent at 24–36 months, and become sexually mature at the age of three years. Young cubs ride on their mother's back when she walks, runs, or climbs trees until they reach a third of her size. Individual riding positions are maintained by cubs through fighting. Intervals between litters can last two to three years.

, and bees, which they locate by smell. On arriving at a mound, they scrape at the structure with their claws until they reach the large combs at the bottom of the galleries, and disperse the soil with violent puffs. The termites are then sucked up through the muzzle, producing a sucking sound which can be heard 180 m away. Their sense of smell is strong enough to detect grubs 3 ft below ground. Unlike other bears, they do not congregate in feeding groups. Sloth bears may supplement their diets with fruit, plant matter, carrion, and very rarely other mammals. In March and April, they eat the fallen petals of mowha trees and are partial to

. This sticky substance hardens into a dark yellow, circular, bread-like mass which is fed to the cubs. This "bear's bread" is considered a delicacy by some of India's natives. Rarely, Sloth bears can become addicted to sweets in hotel waste, visiting rubbish bins, even inside populated towns, all year long. Their diet includes animal flesh.
In Neyyar Wildlife Sanctuary, Kerala, seeds of six tree species eaten and excreted by sloth bears (''Artocarpus hirsuta'', ''A. integrifolia'', ''Cassia fistula'', ''Mangifera indica'', ''Zizyphus oenoplina'') did not see significantly different percentages of germination (appearance of cotyledon) when compared to germinated seeds that had not been passed through the gut of the bears. However, seeds germinated much faster after being ingested by bears for three species, ''Artocarpus hirsuta, Cassia fistula,'' and ''Zizyphus oenoplina''. This experiment suggests that sloth bears may play an important role in seed dispersal and germination, with effects varying by tree species.

s occasionally prey on sloth bears. Tigers usually give sloth bears a wide berth, though some specimens may become habitual bear killers, and it is not uncommon to find sloth bear fur in tiger scats. Tigers typically hunt sloth bears by waiting for them near termite mounds, then creeping behind them and seizing them by the back of their necks and forcing them to the ground with their weight. One tiger was reported to simply break its victim's back with its paw, then wait for the paralysed bear to exhaust itself trying to escape before going in for the kill. When confronted by tigers face to face, sloth bears charge at them, crying loudly. A young or already sated tiger usually retreats from an assertive sloth bear, as the bear's claws can inflict serious wounds, and most tigers end the hunt if the bears become aware of the tiger's presence before the pounce. Sloth bears may scavenge on tiger kills. As tigers are known to mimic the calls of

.
Fewer than 20,000 sloth bears are estimated to survive in the Indian subcontinent and Sri Lanka. To address the human-bear conflict, people may be educated about the conservation ethics, particularly among locals. To resolve this conflict, the basic issue of deteriorating habitat, which is the reason for the conflict between people and bears, improvements through government or community-based reforestation programmes, may be promoted.
Sloth bears have also been found dead in traps, electrocuted, or killed by other means by poachers, with body parts (i.e. canines, claws, gall bladder, paws, etc) usually removed for the illegal wildlife trade.
The population of sloth bears grows when they live in high-profile reserves that protect species, such as tigers and elephants. Directly managed reserves could conserve the sloth bear, hence such reserves must be supported. Managing garbage, especially hotel waste with foods, is essential in situations where sloth bears get used to entering towns with an increase in the number of accidental attacks on humans.
The government of India has banned use of sloth bears for entertainment, and a 'Sloth Bear Welfare Project' in the country has the objective of putting an end to their use for entertainment. However, their number in such activity is still large. Many organisations are helping in the conservation and preservation of sloth bears in safe places. Sloth bears previously used for entertainment are being rehabilitated in facilities like Agra Bear Rescue Facility run by Wildlife SOS and others. Major sloth bear sanctuaries in India include the Daroji Sloth Bear Sanctuary in Karnataka, and Jessore Sloth Bear Sanctuary in Gujarat. A Sloth Bear Conservation Reserve is proposed in Mirzapur district of Uttar Pradesh.
Relationships with humans
Attacks on humans
Sloth bears are one of the most aggressive extant bears and, due to large human populations often closely surrounding reserves that hold bears, aggressive encounters and attacks are relatively frequent, though in some places, attacks appear to be a reaction to encountering people accidentally. In absolute numbers, this is the species of bear that most regularly attacks humans. Only the Himalayan black bear subspecies of Asian black bear is nearly as dangerous.Bargali, H. S., Akhtar, N., & Chauhan, N. P. S. (2005). ''Characteristics of sloth bear attacks and human casualties in North Bilaspur Forest Division, Chhattisgarh, India''. Ursus, 16(2), 263–267. Sloth bears likely view humans as potential predators, as their reactions to them (roaring, followed by retreat or charging) are similar to those evoked in the presence of tigers and leopards. Their long claws, which are ideally adapted for digging at termite mounds, make adults less capable of climbing trees to escape danger, as are other bears such as Asian black bears. Therefore, sloth bears have seemingly evolved to deal with threats by behaving aggressively. For the same reason, brown bears can be similarly inclined, accounting for the relatively high incidence of seemingly non-predatory aggression towards humans in these two bear species.
According to Robert Armitage Sterndale, in his ''Mammalia of India'' (1884, p. 62):
Captain Williamson in his ''Oriental Field Sports'' wrote of how sloth bears rarely killed their human victims outright, but would suck and chew on their limbs till they were reduced to bloody pulps. One specimen, known as the sloth bear of Mysore, was responsible for the deaths of 12 people and the mutilation of 24 others. It was shot by Kenneth Anderson. Although sloth bears have attacked humans, they rarely become man-eaters. Dunbar-Brander's ''Wild Animals of Central India'' mentions a case in which a sow with two cubs began a six-week reign of terror in Chanda, a district of the

considered them to be more dangerous than American black bears. Unlike some other bear species, which at times make mock charges at humans when surprised or frightened without making physical contact, sloth bears frequently appear to initiate a physical attack almost immediately. When people living near an aggressive population of sloth bears were armed with rifles, it was found that it was an ineffective form of defense, since the bear apparently charges and knocks the victim back (often knocking the rifle away) before the human has the chance to defend themself.

, most of the attacks by sloth bears occurred outside forests, when they entered settlements and farmlands in search of food and water.
In Mount Abu town in southern Rajasthan, sloth bears attacked people inside towns where they were seeking hotel waste in rubbish bins and encountered people by chance. Though such attacks were concomitant with increasing tourism activity, quite remarkably, local residents have not retaliated against the sloth bears. The absence of retaliation in many locations of India appears related to cultural norms and the dominant religion Hinduism where nature and animals are worshipped as deities.
Hunting and products
One method of hunting sloth bears involved the use of beaters, in which case, a hunter waiting on a post could either shoot the approaching bear through the shoulder or on the white chest mark if it was moving directly to him. Sloth bears are very resistant to body shots, and can charge hunters if wounded, though someone of steady nerves could score a direct hit from within a few paces of a charging bear. Sloth bears were easy to track during the wet season, as their clear footprints could be followed straight to their lairs. The majority of sloth bears killed in forests were due to chance encounters with them during hunts for other game. In hilly or mountainous regions, two methods were used to hunt them there. One was to lie in wait above the bear's lair at dawn and wait for the bear to return from its nocturnal foraging. Another was to rouse them at daytime by firing flares into the cave to draw them out. Sloth bears were also occasionally speared on horseback. In Sri Lanka, the

It was even taught numerous tricks, such as cradling a woodblock like a baby or pointing a bamboo stick like a gu Dancing bears were historically a popular entertainment in India, dating back to the 13th century and the pre- Mughal era.

Despite a ban on the practice that was enacted in 1972, as many as 800 dancing bears were in the streets of India during the latter part of the 20th century, particularly on the highway between Delhi, Agra, and Jaipur. Sloth bear cubs, which were usually purchased at the age of six months from traders and poachers, were trained to dance and follow commands through coercive stimuli and starvation. Males were castrated at an early age, and their teeth were knocked out at the age of one year to prevent them from seriously injuring their handlers. The bears were typically fitted with a nose ring attached to a four-foot leash. Some were found to be blind from

In 2009, following a seven-year campaign by a coalition of Indian and international animal welfare groups, the last Kalandar dancing bear was set free. The effort to end the practice involved helping the bear handlers find jobs and education, which enabled them to reduce their reliance on dancing-bear income.

to the wolf cubs of the Seeonee wolf pack, as well as to his most challenging pupil, the "man-cub" Mowgli. Robert Armitage Sterndale, from whom Kipling derived most of his knowledge of Indian fauna, used the Hindustani word ''bhalu'' for several bear species, though Daniel Karlin, who edited the Penguin Classics reissue of ''The Jungle Book'' in 1989, stated, with the exception of colour, Kipling's descriptions of Baloo are consistent with the sloth bear, as brown bears and Asian black bears do not occur in the Seoni area where the novel takes place. Also, the name "sloth" can be used in the context of sleepiness. Karlin states, however, that Baloo's diet of ".. only roots and nuts and honey" is a trait more common to the Asian black bear than to the sloth bear.
