Lumbricus terrestris

An earthworm's body is made up of ring-like segments called annuli, those are covered by hairs that help the worm in movement and digging. Earthworms are indigenous to europe, but are now abundant in North America and Western Asia. An earthworm's niche is that its very flexible and boneless this helps them crawl into small holes through the dirt. many species that feed on earthworms are birds and mammals and earthworms get their nutrients through dirt so they don't exactly have a prey to go for.


Students will learn about the internal and external anatomy of an earthworm. Student will focus on the organs,the digestive system, and how it all functions. They will also describe the appearance and placement of organs.

A massive Australian earthworm can grow up to 9 feet long!
