The earthworm (Lumbricus terrestris), belongs to the kingdom Anamalia; the phylum Annelida; the class Clitellata; the order Haplotaxida; the family Lambricicdae; the genus Lumbricus; and the species Terrestris. Earthworms live in the soil, where they feed on leaves, feces, organic or decaying plant matter. They dwell in the soil; also known as detritivores. Predators to the earthworm include snaks, birds, rodents, even insects, sometimes Sarah (lol: refer to picture above). They can have symbiotic relationships with the bacteria that can live in their digestive systems. Some adaptations include the setae (hairs on segments) to help give the earthworms the grip to move through soil. A nutritional adaptation might be the pharynx: an earthworm pushing it out of its mouth to grasp the food, then pulling it back into the mouth for digestion to begin. (Gross!)
Earthworms are very interesting creatures!

Earthworms & Evolution
Humans <3 Earthworms!
“Earthworms are more important to the life of this planet than humans are, and if earthworms disappear, we humans will follow very soon after” - Daniel Quinn. Whoa. Deep.
Earthworms affect the soil that humans plant food in. This is an example of the relationship between humans and earthworms.
