Sloth Bear (Melursus ursinus) lives in indian subcontinent forests across Indian subcontinent. It feeds on insects & fruit. Its conservation status is Vulnerable.
Fascinating facts about the Sloth Bear
- A full-grown sloth bear can weigh up to 192 kg (423 lb), with females typically ranging 55-105 kg and males 80-145 kg, while the average Nepalese female is 95 kg and male 114 kg. Their shoulder height spans 60-92 cm and body length reaches 1.9 m. These dimensions, especially the massive 10 cm (4 in) sickle-shaped claws, let them dig deep into termite mounds, a key adaptation for their insect-rich diet.
- Sloth bears give birth after a 210-day gestation, usually delivering one or two cubs in December or early January in India, while Sri Lankan bears can breed year-round. Newborns are blind for about three weeks, start walking at one month, and stay with their mother for up to three years before reaching sexual maturity at three years old.
- Fewer than 20,000 sloth bears survive across the Indian subcontinent and Sri Lanka, earning them a Vulnerable status on the IUCN Red List. Habitat loss, poaching for claws and gall bladders, and conflict with humans are the main drivers of decline. Protecting large, well-managed reserves where tigers and elephants also thrive can boost bear numbers, showing that ecosystem-wide conservation benefits multiple flagship species simultaneously.
- When sloth bears raid a termite mound, they use their 10 cm claws to scrape away soil, then vacuum up insects through a long, flexible lower lip, producing a sucking sound audible up to 180 m away. Their sense of smell can detect grubs three feet below ground, and the soil they ingest often damages their teeth, leaving adult teeth in poor condition. This extreme feeding method lets them exploit a food source that is available year-round.
- Recent deaths of three sloth bears in Sri Lanka's Wilpattu National Park sparked concern because the carcasses were heavily infested with ticks, suggesting tick-borne fever, while the region also faces an African swine fever outbreak among wild boars. Although no ASF transmission to bears has been confirmed, the combination of disease risk and a reported 20 % smaller body size compared to Indian bears highlights the fragile health of this isolated subspecies.

About the Sloth Bear
In the scorching forests of the Indian subcontinent, the sloth bear lumbers through the underbrush with a deliberate, unhurried gait, its shaggy coat a testament to its ability to thrive in one of the most unforgiving environments on Earth. As it moves, the bear's long, curved claws dig gently into the earth, a subtle reminder of the powerful strength that lies beneath its languid exterior, a strength that allows it to rip apart termite mounds with ease. With a quiet intelligence in its eyes, the sloth bear navigates its domain, a realm of scrubby trees and dusty clearings, where its very existence is a remarkable testament to adaptability and resilience.
