Any planktonic marine member of the class Scyphozoa (phylum Cnidaria), a group of invertebrate animals composed of about
200 described species, or of the class Cubozoa (20 species). The term is
also frequently applied to certain other cnidarians (such as members of
the class Hydrozoa) that have a medusoid (bell- or saucer-shaped) body
form, as, for example, the hydromedusae and the siphonophores (including
the Portuguese man-of-war).
