Earthworms by Casey Earthworms are invertebrates. That means they have no backbone. Earthworms are made up of things called segments. The scientific name for earthworms is annelids. Earthworms are not like any other animal because they don't have eyes, ears or legs.
Earthworms have a mouth, head, tail and a saddle that is the middle of their body.
Earthworms are found in dark places because they do not like the light. Earthworms eat egg shells, orange peels and banana peel. When earthworms eat the food passes through their body and it comes out of the tail as a very rich fertile material. Did you know that if you cut an earthworm past its saddle, it will grow back its tail. But if you cut an earthworm before its saddle it will not grow back its tail and it will die.
