Coelenterates or "jellyfish, anemones, corals, and hydras" Small species feed on food particles in the water. Larger jellyfish species are predators on fish or invertebrates. They immobilize their prey by using special stinging cells. Jellyfish have no digestive tract therefore food and waste must be passed in and out through the same opening.
Actually, the Echinoderms are a pretty diverse Phylum, including sea stars (aka starfish), crinoids, sea cucumbers and sea urchins - each of which have very different feeding habits and methods of obtaining their food.
Many sea stars are predators, feeding on molluscs like clams by prying apart their shells and actually everting their stomach inside the shell to digest the meat.
Crinoids are filter feeders, using their long arms to capture food particles wafting past in the currents.
Sea urchins have powerful grinding mouthparts that allow them to chew apart rock-hard coral, or scrape algae and kelp from the rocks.
There's no one food or technique that's shared by all Echinoderms.Some coenlenterates move while others do not. Jellyfish are examples of coenlerates that travel while sea anemes are examples of ones that are still.
