Cnidaria- Chrysaora fuscenscens 

The organisms in Phylum Cnidaria are radially symmetrical.  Their bodies are multicellular, with a few tissues, and some organelles.  The body contains an internal cavity as well as a mount, and may have a minimal skeleton of chiton or calcium carbonate. 

Two different forms of Cnidaria exist, medusa and polyp; both forms are mostly carnivorous, or otherwise filter feeders.  The reproductive system can be asexual or sexual.  They have a simple, net-like nervous system.  The organisms have a distinct larval stage which is planktonic.  They live in aquatic environments, mostly marine.

Examples of organisms found in Phylum Cnidaria include: Sea Anemones, Corals, and Jellyfish.
