How do Earthworms Move?
They never move!! They just sit in one place!!
Oh AumSum!!
In order to move forward an Earthworm first extends the front part of its body using its muscles.
Once its front body is extended, tiny hairlike structures called setae come out of its front part and insert themselves into the soil. Now these inserted setae act as an anchor for the earthworm to pull its rear part forward.
Once the rear part of the body has moved forward, the earthworm retracts the setae extended from its front part and inserts the setae from its rear part into the soil.
Now these inserted setae act as an anchor for the earthworm to again pull its front part forward. The earthworm keeps on repeating this cycle in order to move forward.
