What do Echinoderm eat?

Answer 1

Depending upon the type of echinoderm, they can eat just about anything smaller than themselves.

Sea stars are typically predators that eat clams, other sea stars, sea cucumbers. Often, as well, sea stars eat animals that don't move such as sponges or corals.

Most sea urchins eat algae.

Many sea cucumbers use their sticky tentacles to catch small floating organisms called plankton. Others mop the bottom to eat detritus. In many regions, the populations of echinoderms living on the ocean bottoms are very important predators and determine what other animals can live there.
