🐻Bears
곰은 식육목 곰과에 속하는 포유동물이다. 어린 개체는 능소니라 부른다. 꼬리가 짧고 후각과 청각이 발달했으며, 발가락이 다섯 개이다. 길고 빽빽한 털로 덮여 있으며, 커다란 몸에 강한 팔다리를 갖고 있다. 곰은 식육목에 속해 있지만, 북극곰을 제외하고 거의 대부분은 식물성 물질을 먹는 초식 위주 잡식성이다. 대왕판다 같은 경우는 거의 대나무만 먹으므로 초식성으로 한다. 하지만 내장구조가 다른 육식동물들과 비슷하기 때문에 식물성 물질을 초식동물처럼 제대로 소화시키지는 못한다. 그렇기 때문에 곰은 특정한 시기에만 집중적으로 먹기도 하며, 한번에 먹는 양도 많다.
