Lizards are members of the reptile family. Other members are snakes, turtles, crocodiles and alligators. Lizards have several things in common with other reptiles. All reptiles are cold-blooded. They cannot control their own body temperature. It is controlled by their surroundings. Lizards must work to maintain their temperature. Another characteristic which lizards have in common with all reptiles is that their skin is made of scales.
蜥蜴是爬行动物的一员。爬行动物还包括蛇，龟，鳄鱼和短吻鳄。蜥蜴与其他爬行动物有几个共同点。所有的爬行动物是冷血的。他们无法控制自己的体温。他们的体温由他们所处的环境决定。蜥蜴必须努力保持其温度。而蜥蜴与所有爬行动物的另一个共同点是他们的皮肤是由鳞片组成。
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。
Lizards have a simple body shape. They have a head, a pair of legs, a long body, another pair of legs and a tail. Their tails can help them balance, swim, or grab tree branches. Some lizards use their tails as a weapon. They can also wiggle away from a predator which grabs their tail. Certain muscles will cause it to fall off, but the tail still moves. The predator watches the tail, and the lizards can escape. Then lizards can grow a new tail. Lizards range in size from one and one-half inches long to seven and one-half feet. The Komodo dragon is the biggest lizard. The Komodo dragons live in Indonesia. The smallest lizards live in the British Virgin Islands.
蜥蜴的体型十分简单。他们有一个头，一双腿，一个修长的身体，另一对腿和一根尾巴。它们的尾巴能帮助他们平衡，游泳，或抓住树枝。有些蜥蜴用它们的尾巴作为武器。当捕食者抓住他们尾巴的时候，他们可以通过扭动尾巴进而逃跑。而某些肌肉会使尾巴脱落，但脱落的尾巴却仍然是活动的。使捕食者盯着蜥蜴的尾巴，蜥蜴便得以逃脱。不久后蜥蜴就长出新的尾巴。蜥蜴的体型从七又二分之一英尺到一又二分英寸不等。科莫多巨蜥是最大的蜥蜴。科莫多巨蜥生活在印度尼西亚。最小的蜥蜴生活在英属维尔京群岛。
