The Fish


Fish existed on the earth for more than 440 million years. The whale  is the largest fish which can reach 50 feet in length. Most fish reproduce by laying eggs. Some fish, such as great white sharks, give birth to live babies called pups. They have good senses of sight, taste, touch, hear and smell.

Fish hear using their ears that reside inside their body. Sharks are the only fish that have eyelids. Fish extract oxygen from the water around them with their gills. Fish has a cover of scales, which are often covered in a layer of slime to help their movement through water. Most fish have taste buds all over their body.
