What helps an earthworm move?
An earthworm moves using circular and longitudinal muscles, as well as bristles called setae. The earthworm can push the setae out of its body to grab the soil around it. To move forward, the worm uses its setae to anchor the front of its body and contracts the longitudinal muscles to shorten its body.
How do earthworms respond to their environment?
When earthworms feel vibrations they move closer to the surface, in case the vibrations are caused by an underground predator, such as a mole, searching for food. Earthworms are sensitive to light and usually are found above ground at night only. Earthworms lose moisture through their skin.
How do earthworms walk?
Movement. Earthworms use their muscles to extend their bodies when moving forward. Once they extend, they extend tiny hairlike structures known as setae from inside their bodies down into the soil. These setae act as an anchor so that the worms can then pull the rear part of their bodies forward.
How does earthworm fix its body parts to the ground class 6?
earthworm does not have bones. It has muscles which help to extend and shorten the body. During movement, the earthworm first extends the front part of the body, keeping the rear portion fixed to the ground. Under its body, it has a large number of tiny bristles (hair like structures) projecting out.

Do earthworms die if cut in half?
If an earthworm is split in two, it will not become two new worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum. But the original tail of the worm will not be able to grow a new head (or the rest of its vital organs), and will instead die.
