The sun bear is a species in the family Ursidae occurring in the tropical forests of Southeast Asia. It is the smallest bear, standing nearly 70 centimetres at the shoulder and weighing 25–65 kilograms. It is stockily built, with large paws, strongly curved claws, small rounded ears and a short snout. They are very aggressive bears, probably the most aggressive, and they will attack without being provoked. Sun Bears inhabit the lowland tropical forests of South East Asia. They are excellent climbers and they spend a large amount of their time in the trees. Social System. Little is known about the behavior or social structure of sun bears. Except females with their offspring, sun bears usually appear to be solitary. They may congregate to feed from large fruiting trees, but this behavior appears to be rare.
