They use their hydrostatic skeleton.
Sea anemones and earthworms.
False!
Some animals have that a hydrostatic skeleton include jellyfish and earthworms. Additional examples include sea urchins and starfish. As a result of their flexibility, hydrostatic skeletons are particularly useful for locomotion.
Animals like jellyfish, earthworms, and sea anemones have a hydrostatic skeleton. This system uses fluid pressure within a cavity to provide structure and support to the organism. Hydrostatic skeletons allow for flexibility and movement in these soft-bodied animals.

No bones, but they do have a hydrostatic skeleton.
earthworms have a hydrostatic skeleton. An Earthworm is able to move with the help of a fluid-filled chambers functioning like a hydro-skeleton. The earthworm movement in the soil helps in converting large pieces of organic to matter. Earthworms keep the soil structure open through its burrowing actions.

The phylum that has organisms known for a hydrostatic skeleton is the phylum Mollusca. This group of animals, such as snails and squids, have a fluid-filled cavity that provides support and structure to their bodies.
