Annelid Worms - Earthworms

The scientific name for earthworms is Lumbricina. The reddish-gray colored common earthworm, often called a night crawler in the United States, is familiar to anyone with a fishing rod or a garden. They are indigenous to Europe, but are now abundant in North America and western Asia. Typically only a few inches (6 or 7 centimeters) in length, some members of this species have been known to grow to a rough 14 inches (35 centimeters). Earthworms' bodies are made up of ring-like segments called annuli These segments are covered in setae, or small bristles, which the worm use to move and burrow.
