What are fish? What does a fish look like? You might be surprised.

什么是鱼呢？ 鱼长什么样子呀？ 答案说不定会让你大吃一惊哦。

Fish can be very big or very small. This shark is the largest fish in the world. Like other fish, it has a backbone. It breathes through gills. It has fins to help it swim.

鱼可以特别大，也可以特别小。 这条鲨鱼是世界上最大的鱼类。 和其他鱼一样，它长有脊椎。 它用鳃呼吸。 它长着鱼鳍来帮助自己游泳。

A horse or a fish? Some fish look like other animals. This fish is called a seahorse. The fin on the back of the seahorse beats very fast. This is how the seahorse moves around.

是马还是鱼呀？ 有些鱼长得和其他动物很像。 这种鱼叫做海马。 海马背上的鱼鳍摆动得非常快。 海马就是靠这种方式四处移动的。

A seahorse uses its tail to grab onto plants in the water. It can hide in the plants where no hungry fish can find it.

海马用自己的尾巴勾住水里的植物。 它可以躲在植物丛里，饿肚子的鱼都找不到它。

A snake or a fish? This fish, called an eel, looks a lot like a snake. It swims by moving its whole body. It can swim forward and backward. It breathes by opening and closing its mouth to pump water over its gills.

是蛇还是鱼呀？ 这种鱼叫鳗鱼，长得和蛇特别像。 它靠扭动整个身体来游泳。 它既能向前游，也能向后游。 它通过一张一合嘴巴把水输送到自己的鳃上来呼吸。
