The earthworm ( Lumbricus terrestris) is in the Phylum Annelida. Earthworms live within the soil and arent typically found in dry or cold places. The earthworms have adapted to live in these places. For example earthworms have setae, briskly hairs on their segments, which help with movement underground. They also dont have any appendages or antenae which alow them to fit into tighter spaces without getting in the way.
The earthworm has many predators. Some predators of the earthworm are snakes, birds, and rodents. The earthworm is a decomposer, eating dead or decaying matter. Like all organism the earthworm has different stages within it's lifespan.
