补充资料:动物的牙齿
牙齿作为最重要的器官,在动物的生命历程中起了至关重要的作用。食肉动物在猎获食物的各个环节:猎杀、叼拿、弄碎肢解,都无一不运用牙齿作为天然工具。失去一颗犬牙的老虎就再也无法猎杀大型有蹄动物。
啮齿动物牙齿的工作量相当繁重,其损耗程度也十分惊人,因而它们的牙齿总是不断地生长。老鼠的门牙每个月可长出3厘米,倘若不磨损的话,日积月累长下去,到老年它们的牙齿就会长达70~100厘米。
大象牙齿的兴衰则与其寿命息息相关。大象以植物为食,对付坚韧的植物纤维需要用臼齿。承担如此重任的仅有两对工牙,而其余五对暂时“休闲”的牙,要依次等待老牙磨损脱落,才能顶替为工牙。随着牙齿的新老更替,大象也逐渐衰老,甚至死亡。
鲨鱼的牙齿令人恐惧。其牙齿布满上下颌,整齐地排列成行,处于一种“冲锋陷阵”、“前仆后继“的运动状态。齿尖朝后,呈“倒刺”状防止猎物脱逃。而且牙齿经常进行更新,使鲨鱼在一生中都保持着良好的“战斗力”。
鲤科鱼的牙齿不是长在嘴里,而是长在喉咙里,因为这里是它磨碎食物的第一加工场所。
