Earthworms

 Earthworms

    The earthworm is more than fish bait and bird food. They are nature's workman. Earthworms improve soil for humans, plants, and animals. The tunnels they create help air and water reach deeper parts of the soil. More air and more water make for healthier soil.

    Did you know the diet of an earthworm is the dirt itself? These worms eat the soil they live in. This food source is great for the worm but not for plants. The waste released by the worm is then used to feed the plants because it has a lot of nutrients. 

    If you were to look really closely at the earthworm's body it looks like they are joined together with rings. They are actually put together with about 150 different segments. This helps the worm to move as each segment has muscles and bristles. The bristles are what give the worm control when moving through the soil. The different segments to the earthworm are also why they can survive and regrow parts of their body back if something pulls it apart.

    Earthworms have no lungs to help them breathe. Instead, they breathe through their skin. Their skin cannot dry out or they will not survive.
