Where do Sun Bears live?
Sun bear
Sun bears are found in the tropical rainforest of Southeast Asia ranging from northeastern India, Bangladesh, Myanmar, Thailand, Peninsular Malaysia, Laos, Cambodia, Vietnam to southern Yunnan Province in China, and on the islands of Sumatra and Borneo in Indonesia. They now occur very patchily through much of their former range, and have been extirpated from many areas, especially in mainland Southeast Asia. Their current distribution in eastern Myanmar and most of Yunnan is unknown.
The bear’s habitat is associated with tropical evergreen forests."Helarctos anmamiticus", described by Pierre Marie Heude in 1901 from Annam, is not considered a distinct species, but is subordinated (a junior synonym) to "H. m. malayanus".
Brown bear
The normal range of physical dimensions for a brown bear is a head-and-body length of and a shoulder height of . The tail is relatively short, as in all bears, ranging from in length. The smallest brown bears, females during spring among barren-ground populations, can weigh so little as to roughly match the body mass of males of the smallest living bear species, the sun bear ("Helarctos malayanus"), while the largest coastal populations attain sizes broadly similar to those of the largest living bear species, the polar bear. Interior brown bears are generally smaller than is often perceived, being around the same weight as an average lion, at an estimate average of in males and in females, whereas adults of the coastal populations weigh about twice as much. The average weight of adult male bears from 19 populations, from around the world and various subspecies (including both large- and small-bodied subspecies), was found to while adult females from 24 populations were found to average .
