How Do Echinoderms Breathe?

Answer

On the ventral side of an echinoderm (say, a sea star, for example) there are hundreds of tiny feet arranged into rows on each appendage. These are called tube feet. By varying the internal water pressure, the echinoderm can extend and contract its tube feet for locomotion, food collection, and respiration.
