Abstract
The Scyphozoa constitute one of the four classes of living cnidaria. The members of the phylum Cnidaria are characterized by the possession of intrinsic cnidae: intracellular organelles consisting of a capsule and an attached hollow thread. Cnidarian animals consist of two epithelial body layers, the epidermis and gastrodermis, separated by a gelatinous connective tissue, the mesoglea. These three layers form a sac around the gastrovascular cavity or coelenteron which usually has a single opening, the mouth. Typically tentacles form a ring around the margin of an oral disc surrounding the mouth.
