The Rabbit, Oryctolagus cuniculus 收藏

兔子,Oryctolagus cuniculus
摘要
The laboratory rabbit is descended from the European rabbit (Oryctolagus cuniculus) of the order Lagomorpha. This order includes hares, rabbits, and pikas. Lagomorphs, like rodents, lack canine teeth and possess rootless, chisel-shaped incisors, separated from the premolars by a space (diastema). Lagomorphs, however, have six incisors, in comparison to the rodents’ four. The extra pair is small and is placed directly behind the large upper pair; they are rounded, lack a cutting edge, and are only moderately useful.

实验室兔是Lagomorpha的欧洲兔(Oryctolagus cuniculus)的后代。这个订单包括野兔,兔子和鼠兔。像啮齿类动物一样,兔形目缺乏犬齿,并且具有无根的凿形切牙,通过空间(diastema)与前磨牙分开。然而,与啮齿动物的四个相比,Lagomorphs有六个门牙。额外的一对很小,直接放在大的上部对后面;它们是圆形的,没有前沿,只是适度有用。
