Anthoathecata
Anthoathecata, or the athecate hydroids, are an order of hydrozoans belonging to the phylum Cnidaria. A profusion of alternate scientific names exists for this long-known, heavily discussed, and spectacular group. It has also been called Gymnoblastea and (with or without an emended ending ''-ae''), Anthomedusa, Athecata, Hydromedusa, and Stylasterina. There are about 1,200 species worldwide.Schuchert, P. (2014). Anthoathecata. Accessed through: Schuchert, P. (2014) World Hydrozoa database at http://www.marinespecies.org/hydrozoa/aphia.php?p=taxdetails&id=13551 on 2014-10-31 These hydrozoans always have a polyp stage. Their hydranths grow either solitary or in colonies. There is no firm perisarc around the polyp body. The medusae, or jellyfish, are solitary animals, with tentacles arising from the bell margin, lacking statocysts but possessing radial canals. Their gonads are on the manubrium ("handle").Bouillon, J.; Gravili, C.; Pagès, F.; Gili, J.-M.; Boero, F. (2006). An intro ...

Filifera
Filifera is a suborder of hydrozoans in the order Anthoathecata. They are found in marine, brackish and freshwater habitats. Characteristics Members of this suborder are characterised by the filiform tentacles of the polyps which do not terminate in knobs. The rose corals, family Stylasteridae, secrete calcium carbonate exoskeletons around a network of stolons. Families According to the World Register of Marine Species, the following families are found in this suborder : * Australomedusidae Russell, 1971 * Axoporidae Boschma, 1951 † * Balellidae Stechow, 1922 *Bougainvilliidae Lütken, 1850 * Bythotiaridae Maas, 1905 *Clathrozoellidae Peña Cantero, Vervoort & Watson, 2003 * Cordylophoridae von Lendenfeld, 1885 * Cytaeididae L. Agassiz, 1862 * Eucodoniidae Schuchert, 1996 *Eudendriidae L. Agassiz, 1862 * Heterotentaculidae Schuchert, 2010 *Hydractiniidae L.

Cnidarians
Cnidaria () is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments, predominantly the latter. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. Cnidarians mostly have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths surrounded by tentacles that bear cnidocytes. Both forms have a single orifice and body cavity that are used for digestion and respiration. Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and Scyphozo ...
