Introduction
Earthworm Locomotion and Its Importance To Soil
Lumbricus (earthworm) is an example of the phylum Annelida. The body of annelids is divided into sections by septa (membranes). Each section is a compartment. Its movement is a result of the action of body-wall muscles on incompressible fluids in the compartments (segments). Therefore, a compartment that contracts in diameter must simultaneously increase in length. There are
