booklet questions
What kind of skeletal system does the worm have?
The earthworm does not have a skeletal system
How does this work?
The worm relies on its muscular system to hold it together and move, it moves by squeezing the circular muscles of each segment to make their body extend forward. Then they grip the surface and contract their longitudinal muscles so their body pulls up to it's front end.
