Sea Anemone

Sea anemones are a group of predatory marine invertebrate animals constituting the order Actiniaria. Because of their colourful appearance, they are named after the Anemone, a terrestrial flowering plant. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and hydra. Unlike jellyfish, sea anemones do not have a medusa stage in their life cycle.
