What defines this group — Cnidarians (corals, anemones, jellyfish)
Corals, anemones and jellyfish: the same simple animal, anchored to the bottom or drifting in open water.
- All armed with cnidocytes, harpoon cells that fire on contact.
- A body arranged in rays around a single opening, serving as both mouth and exit.
- Hard corals host algae in their tissue: it is their departure that causes bleaching.
