How Does Earthworm Change Its Shape? To keep shape changes from getting too extreme in the worm body, strong connective-tissue fibers spiral around the segments. … In earthworms, each segment can move independently, so that alternating contractions between the two different sets of muscles in many different segments create shape changes all along the body.
How Does Earthworms Impact The Amount Of Biomass An Ecosystem Can Support?

These are cells that allow the earthworm to taste things and are tiny sense organs which detect chemicals in the soil. The muscles make movements in response to touch and taste. Which
What Is The Segmented Body Of Earthworm Called? Metameric bodies are divided into segments called annuli. The annuli are covered in tiny hairs called setae. Setae help the worms move.
