Filifera
Filifera is a Order (biology)#Hierarchy of ranks, suborder of hydrozoans in the Order (biology), 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 family (biology), 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.

Anthomedusae
Anthoathecata, or the athecate hydroids, are an order (biology), order of hydrozoans belonging to the phylum (biology), phylum Cnidaria. A profusion of alternate scientific names exists for this long-known and heavily discussed 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 (zoology), polyp stage. Their wiktionary:hydranth, hydranths grow either solitary or in colonies. There is no firm perisarc around the polyp body. The medusa (biology), 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").Bou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
