Starfish do not actually swim; instead, they crawl. Starfish have tiny tube-like ‘feet’ all over their underside, which enables to them to crawl very slowly from one point to the other. Starfish can often give the appearance of swimming when the ocean current picks them up and makes them waterborne, but the starfish is not actually swimming when this happens.
Starfish, or sea stars (they are actually echinoderms, not fish) don’t swim but crawl along the ocean floor. Within their body they have a network of tubes , the tips of which extend to the outside, and are known as tube feet. These tube feet allow them to crawl at rates up to 2.5 feet per minute, as well as cling to surfaces.
