Plumularioidea
Plumularioidea is a superfamily of hydrozoans in the order Leptothecata. This superfamily unites about 45 genera in the following families: * Aglaopheniidae Marktanner-Turneretscher, 1890 * Halopterididae Millard, 1962 * Kirchenpaueriidae Stechow, 1921 * Phylactothecidae Stechow, 1921 * Plumaleciidae Choong & Calder, 2018 * Plumulariidae McCrady, 1859 * Schizotrichidae Peña Cantero, Sentandreu & Latorre, 2010 These thecate hydroids grow in erect colonies, branched in some species but unbranched in others. Each branch may bear a single or several animals. In the latter case the hydrothecae are arranged in a neat single file; in either case they are not set on stalks but grow from the branches directly. The hydrothecase have a cusped or even rim and instead of a diaphragm a well-defined floor with a hydropore that is usually off-center. The hydranths have a conical hypostome and a single whorl of thread-like tentacles. The gastrodermis contains areas with and o ...

Leptothecata
Leptothecata, or thecate hydroids, are an order of hydrozoans in the phylum Cnidaria. Their closest living relatives are the athecate hydroids, which are similar enough to have always been considered closely related, and the very apomorphic Siphonophorae, which were placed outside the "Hydroida". Given that there are no firm rules for synonymy for high-ranked taxa, alternative names like Leptomedusa, Thecaphora or Thecata, with or without the ending emended to "-ae", are also often used for Leptothecata. Leptothecata is surrounded by a chitinous outer layer as its exoskeleton, including gonophores, their reproductive organ. Leptothecata obtain radial symmetry, in which their gonads can be found in their radial canals. Their morphological characters normally have ranged from benthic to planktonic stages. Characters associated with benthic are the polyps and colony forms, while planktonic is medusae. Leptothecata has a vast and complex variation among all species within the hydrozo ...

Kirchenpaueriidae
Kirchenpaueriidae is a family of hydrozoans in the superfamily Plumularioidea. Their hydrocladia are characteristically set in an alternating fashion as one progresses along the stems, forming two neat rows except in '' Oswaldella laertesi'', which has three such rows. The alternating placement of the hydrocladia can be used to distinguish them from the Plumulariidae Plumulariidae is a family (biology), family of hydrozoans. Genus According to the World Register of Marine Species, the following genus, genera belong to this family: *''Callicarpa (hydrozoan), Callicarpa'' Fewkes, 1881 *''Cladacanthella'' Calde ... which may look superficially similar. There are six genera recognized in the family Kirchenpaueriidae: * '' Halicornopsis'' * '' Kirchenpaueria'' * '' Ophinella'' * '' Oswaldella'' * '' Pycnotheca'' * '' Wimveria'' References * MarineSpecies.org (2008)Kirchenpaueriidae Retrieved 2008-JUL-08. * Schuchert, Peter (2008) Retrieved 2008-JUL-08.

Gonophore
A gonophore is a reproductive organ in Hydrozoa that produces gametes. It is a sporosac, a medusa or any intermediate stage. The name is derived from the Greek words (, that which produces seed) and (, -bearing). Gonophores are borne on branching stalks that grow out as a ring from the hydranth (i.e. the hydroid polyp, bearing a mouth, digestive cavity and tentacles) wall. The germ cells are formed from the inner layer of the entocodon. The entocodon is the primordium (i.e. the first cells that give rise to the development of an organ) of the subumbrella (i.e. the concave oral surface of a medusa) in the development of medusae from the gonophore. The gonophores in the order Leptomedusae are borne on much reduced hydranths and are usually protected in a peridermal (i.e. belonging to a hydroid perisarc) gonotheca. Medusae forming on fully developed hydranths are extremely rare; usually the gonophores develop into medusae or into sessile sporosacs. The gonophores in the superfam ...
