引言 早在恐龙漫步地球之前，鲨鱼就已经生活在海洋里了。 在全世界各地一共能找到数百种鲨鱼。

Sharks are fish, but their skeletons are made of cartilage instead of bones. Cartilage is what gives human ears their shape. Unlike most fish, sharks have rough skin.

鲨鱼属于鱼类，但它们的骨架不是骨头，而是由软骨构成的。 我们人类耳朵的形状也是靠软骨来支撑的哦。 和大多数鱼类不一样，鲨鱼的皮肤摸起来很粗糙。

Sharks have a good sense of smell. They also see well in the dark. Sharks can sense other animals moving in the water.

鲨鱼的嗅觉非常灵敏。 它们在黑暗环境里的视力也很好。 鲨鱼还能感知到水里其他动物的动静。

Description Sharks come in many sizes. Some sharks are only a few inches long. The huge whale shark is the largest fish in the world.

外形介绍：鲨鱼的体型大小各不相同。 有些鲨鱼只有几英寸长哦。 而体型庞大的鲸鲨是世界上最大的鱼类。

Many sharks are dark on the top and light on the bottom. This shading makes it harder for other animals to see them.

很多鲨鱼的背部颜色深，腹部颜色浅。 这样的颜色能让其他动物更难发现它们。
