Actinaria- Sea anemones

Sea anemones are named after the flower of the same name that they resemble. Their column-like bodies are attached to a structure, like a rock or a float, where they wait to catch whatever swims by. They have an oral disk surrounded by stinging tentacles, which they use to stun small fish or shrimp before pulling them into their mouths to digest. Touch them gently and feel the light stickiness of their tentacles!
