← Locomotion means the act / power of moving from place to place, characteristic of the higher animals and some of the lower forms of plant life.
← Earthworm is any one of numerous annelid worms that burrow in soil and feed on soil nutrients and decaying organic matter or any worm of the genus Lumbricus and allied genera, found in damp soil.

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... [continues]
