Tube feet

tube feet -- Extensions of the water-vascular system of echinoderms, protruding from the body and often ending in suckers. May be used for locomotion and/or for maintaining a tight grip on prey or on the bottom.

tube feet (podia) .Numerous small, muscular, fluid-filled tubes projecting from body of echinoderms; part of water-vascular system; used in locomotion, clinging, food handling, and respiration.

tube feet The locomotory organs of Echinoderms, which are protruded from the body by, and are retracted by, fluid pressure from the water vascular system.

It positions itself over a bivalve and attaches tube feet to each side of the shell. By working tube feet in an alternating fashion, it opens the shell open. Only a small crack is needed to insert its cardiac stomach into the prey.

Gas exchange occurs across the skin gills and tube feet. Nitrogenous wastes diffuse through coelomic fluid and across the body wall. Cilia on the peritoneum lining the coelom keep the coelomic fluid moving. Full article ...

Seawater is taken into a system of canals and is used to extend the many tube feet. These have suckers on their tips and aid the animal in attaching itself to solid surfaces. About 6,000 species — all of them marine.

Sea cucumbers will eviscerate themselves (turn themselves inside out) if attacked by a predator and then regenerate their internal organs. They have an endoskeleton and organ systems including a system of sucker-like tube feet.
