	Stingers - known to scientists as Cnidarians (pronounced "Ni-dare-ee-ans") - are an ancient and primitive form of life.
	Stingers include jellies, corals, and anemones. They are the simplest multi-celled animals that have muscles and nerves for movement. Their simple, circular bodies are open at only one end where they have a mouth surrounded by a ring of tentacles filled with stinging cells. Some, like jellies, swim free with their tentacles hanging down; others, like anemones, rest on the sea bottom with tentacles facing up. Some live solitary lives; others, like many corals, live in groups called "colonies."
