An earthworm receives support and shape from its fluid-filled cavity. It has Hydroskelton
Explanation:
The muscle of earthworm encloses with two layers of muscle which is circular and longitudinal. There is fluid cavity between digestive part and muscle. it is called coelom and fluid is coelomic fluid. This fluid work as hydrostatic skeleton.
It provides resistance to muscular contraction. It helps the earth worm to applying the force and change the shape. Mostly hydrostatic Skeleton organism has more or less cylindrical. This type of Skeleton found in soft bodied invertebrates.
