Amphibian

A cold-blooded animal that lives both in water and on land.

What is it?

Amphibians are animals that can live in water and on land. They include frogs, toads, salamanders, and sirens. Most amphibians start life in water with gills, then grow lungs and legs to live on land. But some, like the Western Lesser Siren, keep their gills and stay in water their whole lives. Amphibians have smooth, moist skin and lay eggs in water.

Why it matters

Amphibians are important because they eat insects and are food for other animals. They are also indicators of a healthy environment because their skin absorbs pollution easily.

两栖动物

一种既能在水中又能在陆地上生活的冷血动物。

这是什么?

两栖动物是既能在水中又能在陆地上生活的动物。它们包括青蛙、蟾蜍、蝾螈和美人鱼螈。大多数两栖动物在水中开始生活,有鳃,然后长出肺和腿在陆地上生活。但有些,如西方小美人鱼螈,终身保留鳃并一直生活在水里。两栖动物有光滑湿润的皮肤,并在水中产卵。

为什么重要

两栖动物很重要,因为它们吃昆虫,也是其他动物的食物。它们还是健康环境的指示物种,因为它们的皮肤容易吸收污染物。
