Earthworms are very important animals. They help to expose the soil to air when they are digging tunnels. At the same time， earthworms make the soil rich with their wastes. Good soil can have as many as as 1，000，000 worms per acre!
I have a big family!
There are over 3，000 kinds of earthworms around the world. These animals have a soft body but no backbones. Some earthworms are brown， and some are red. They can be a few inches long， and can also be over 22 feet long. The largest earthworms live in South Africa and Australia.
My body is like a chain of carriages
The earthworm’s body is made up of about 100 segments， like a long chain of carriages. Its mouth is on the first segment and the anus is on the last. But the worm doesn’t breathe with its mouth. It breathes with its skin， and the skin need to be wet. In the front part of the worm， there are the brain and hearts. The earthworm has five pairs of hearts! The rest of the inside of the worm is filled with the intestines. It digests its food with these many intestines. In the middle of the animal， there are big segments. The worm has eggs and gives birth to baby worms with that part.
Soil is my food!
Earthworms eat soil and the organic material in it， for example， the bugs’ body parts. Live plants are never their food， and the worms live friendly with their plant neighbours. Earthworms don’t have eyes， then how can they“see”their food? The animal’s mouth is covered by a thin piece. This part helps the earthworm sense light and shakes as a guidance. The worms have no legs， so how can they move and taste different soils? There are many small hairs on their bodies. With the help of these hairs， the animals have a big meal
