Lizards shed their skin frequently because the skin doesn't grow with them. They have lungs and breathe like humans. They breathe through nostrils above their mouths. They have a special organ on the roof of their mouth. It is a Jacobson's organ. Lizards smell with this. They pick up the smells with their tongues. The smells travel to the Jacobson's organ. Lizards can sense prey this way. Their eyes and ears are located on either side of their heads.
蜥蜴常常蜕皮是因为他们的皮肤不跟随他们自生成长。他们有肺,像人类一样呼吸。他们通过其嘴巴上面鼻孔呼吸。他们口腔上部有一个特殊的器官,被称为雅各布逊氏器。蜥蜴通过这个器官闻到气味。他们用舌头感知气味,随后气味传递到雅各布逊氏器。蜥蜴也能通过这种方式感知猎物。他们的眼睛和耳朵位于头的两侧。
