What can earthworms cling to soil with?

How are earthworms circular and longitudinal muscles used in locomotion?
When the circular muscles contract, they make the worm skinnier. When the longitudinal muslces contract, they make the worm shorter. This series of movements allows for the worm to move forward.

What do the bristles on the underside of the earthworm's body do?
The bristles along the body of an earthworm are called the Setae, they are used as anchors as the earthworm moves along. The earthworms will anchor the rear of the body as it extends the front then anchor the front of the body as it contracts the rear. The setae are extended and contracted in sequence to match the movement of the body.
What are similarities and differences between grasshoppers and earthworms?
