Sea Pens are marine corals who live in clusters on the ocean floor.
Coelenterata is an obsolete term encompassing two animal phyla, the Ctenophora (comb jellies) and the Cnidaria (coral animals, true jellies, sea anemones, sea pens, and their allies).
Cnidarians are jellyfish, sea anemones, sea pens, hydras (cnidarian="nettle" in latin, so they have stinging cells). They eat aquatic animals, from protozoa to fish.
