sloth bearとは 意味・読み方・使い方

The sloth bear (Ursus ursinus =Melursus ursinus), also known as the labiated bear, is a nocturnal insectivorous species of bear found wild within the Indian subcontinent. The sloth bear evolved from ancestral brown bears during the Pleistocene and shares features found in insect-eating mammals through convergent evolution. The population isolated in Sri Lanka is considered as a subspecies. Unlike brown and black bears, sloth bears have lankier builds, long shaggy coats that form a mane around the face, long sickle shaped claws, and a specially adapted lower lip and palate used for sucking insects. Sloth bears breed during spring and early summer and give birth near the beginning of winter. They feed on termites, honeybee colonies and fruits. Sloth bears sometimes attack humans that encroach on their territory. Historically, humans have drastically reduced their habitat and diminished their population by hunting them for food and products such as their baculum and claws. These bears have been used for as performing pets due to their tameable nature.
