简要介绍:

熊科大型食肉动物。是食肉目动物中演化最晚的。分布于欧洲、亚洲、美洲和北非洲。与狗和浣熊近缘，大多数都能爬树并擅长游泳。熊通常为杂食性，但偏爱的食物很不相同（从完全肉食性、以海豹为食的北极熊，到大部分以草为食的眼镜熊都有）。熊断断续续睡过大部分冬天，但这只是长期蛰伏，并非真正的冬眠。野生时能活十五～三十年，圈养时则寿命长得多。

Generally massive, short-legged mammal (family Ursidae), the most recently evolved carnivore, found in Europe, Asia, North and South America, and North Africa. Closely related to the dog and the raccoon, most bears climb with ease and are strong swimmers. As a family, they are omnivores, but dietary preferences vary among species (polar bears feed mainly on seals, the spectacled bear on vegetation, etc.). Though they do not truly hibernate, bears often sleep fitfully through much of the winter. They live 15～30 years in the wild, but much longer in captivity. They have been hunted as trophies, for hides, and for food. See also black bear, brown bear, sun bear.
