How do echinoderms move and get their food?

Answer 1

For the sea star, they grap a clam with all five arms, then it pulls on the tightly closed shell with its tube feet. When the shell opens, the sea star forces its stomach out through its mouth and into the opening between the clam's shells. And then the digestive chemicals break down the clam's tissues, and the star sucks in the partially digested body of its prey.

Answer 2

There are different methods depending on the species. Crinoids and basket stars both filter-feed and sea urchins use a specialized mouthpart called an Aristotle lantern that allows them to feed on algae. Many starfish can "spit" out part of their stomach to engulf the prey and digest them from the outside.

Answer 3

In many different ways, some tend to be passive filter-feeders, absorbing suspended particles from passing water, some are grazers, some are deposit feeders, and some, mainly seastars are active hunters.

Answer 4

All echinoderms have tube feet. These feet have suction disks that enable the animals to crawl or attach themselves to objects.
