A group of seemingly-fluorescent jellyfish in the dark water. Not captive animals. Suitable as a background or photographic print. Jellyfish (also known as jellies or sea jellies) are free-swimming members of the phylum Cnidaria. The jellyfish in these groups are also called, respectively, scyphomedusae, stauromedusae, cubomedusae, and hydromedusae; medusa (plural medusae) is another word for jellyfish. Jellyfish are found in every ocean, from the surface to the deep sea.
