Cnidaria

 [ni-dar´e-ah]
a phylum of marine invertebrates that includes sea anemones, hydras, jellyfish, and corals. See also coelenterata.

Cnidaria

a subphylum of the phylum Coelenterata in some classifications, where the Ctenophora (sea gooseberries) form the other subphylum (see COELENTERATE). However, in more modern classifications the Ctenophora are given the status of a phylum, so that the organisms classified in the Cnidaria (hydroids, jellyfishes, sea anemones and corals) are the only organisms in the new phylum Coelenterata, thus making the term Cnidaria obsolete.

Jellyfish are planktonic, free-swimming, sexually reproducing stages of some cnidarians (animals with unique microscopic intracellular structures called cnidae), collectively named Medusozoa (Marques & Collins, 2004; Collins et al, 2006; Van Iten et al., 2006).

In the case of the Bougainvilliidae, due to lack of information, those three dimensions are not always known, as most studies have focused on the epipelagic zone (0-200 m), as it is typical for Medusozoa (Marques et al., 2003; Segura-Puertas et al., 2003).
