Question

Explain the process of locomotion in earthworms.

Answer 1

The earthworm does not have any internal skeleton. The body is made up of many rings joined end to end and muscles attached to these rings help to extend and shorten the body. The skin of earthworms also has a large number of tiny bristles that help them get a good grip on the ground. Repeated extension and contraction of the body muscles, enable the earthworm to move through the soil.
