		Members of the jellyfish in the class Scyphozoa undergo a complex life cycle including a larval medusa or ephyra stage.
		Other body parts such as the manubrium and the arms are common to both larval ephyrae and mature medusas in the Scyphozoa species.
		The rhopalia are eight sensory organs that are evenly spaced around the fringe of the bell of both stages.

	PHYLUM CNIDARIA: CLASS SCYPHOZOA
		The class Scyphozoa comprises the familiar jellyfishes, of major ecological significance in the plankton.
		Some, including the sessile stauromedusae and the polyp stages of metagenetic free-swimming medusae, occur as part of the benthos.
		The salinity regimes under which the various species of Scyphozoa normally occur in the region is indicated in the check list below using zones established under the "Venice System" (Symposium on the Classification of Brackish Waters, 1958).

		The medusae of Scyphozoa are unique in being typically much larger and anatomically more developed than the polyp.
		Moreover, they are acraspedote, i.e., they lack a velum (a shelf of tissue projecting inward from the margin of the bell in hydromedusae and cubomedusae).
		However, most specialists in the Cnidaria now recognize the Cubozoa as a distinct class (Cubozoa) because of their unique life cycles, morphology, and nematocyst complement.

		Cnidarians are diploblastic -- that is, the body and tentacles consist of two cell layers, the endoderm (sometimes referred to as the gastrodermis) and the ectoderm (the epidermis).
		Indeed, the medusa dominates the life cycle of members of the classes Cubozoa and Scyphozoa (Cubozoa was formerly considered an order of Scyphozoa, and some specialists still consider it as such).

		The phylum is divided into 4 major classes: (1) Hydrozoa (Portuguese man-of-war and fire coral), (2) Scyphozoa (true jellyfish), (3) Cubozoa (box jellyfish), and (4) Anthozoa (sea anemones).
		Sea nettles Chrysaora species and Cyanea species are located along the Atlantic coast, with a high concentration near the Chesapeake Bay.
		Envenomations caused by organisms in the class Scyphozoa are less severe than those caused by Portuguese man-of-war.

		These are sessile cup-shaped forms, and lack a free-swimming medusa.
		The oral arms, often highly branched, have become fused in the center, closing off the central mouth and giving the jellyfish multiple mouth openings at the ends of the lateral arms.
		The Cubozoa, or box jellies, were at one time included as an order of the Scyphozoa, but are now considered to be the sister group of the jellyfish.
