Each segment of the earthworm possesses small hair-like structures called chaetae that are used to help the worm move through the soil. In order to breath, the earthworm can absorb oxygen across the surface of their moist bodies. It can reach a length of 9-30cm and a diameter of 0.6-0.9cm. All earthworms are hermaphroditic, meaning that an individual possesses both male and female reproductive organs. They consume organic matter found in the soil and are important in aeration and fertilization of soil. They also serve as a food source for many mammals and birds.
