Lumbricus terrestris is a species of earthworm commonly known as the "common earthworm."
It is native to Europe and has been introduced to many other regions of the world.
It lives in soil and feed on organic matter such as dead plant material.
Earthworms play an important role in soil ecology and are considered beneficial for soil health as they help to aerate and improve soil structure.
They have a long, cylindrical body that is divided into segments, or annuli.
Earthworms are hermaphroditic, meaning each individual contains both male and female reproductive organs.
They reproduce by mating and producing cocoons that contain several eggs.
