Capitata
Capitata is a suborder of Hydrozoa, a class of marine invertebrates belonging to the phylum Cnidaria. Characteristics Members of this suborder are characterised by the tentacles of the polyps terminating in knobs. In some species these are only present in juvenile forms being replaced in adults by more threadlike tentacles. A high nematocyst concentration is present in the knobs. A few species in this group are better known as their solitary medusa form than as their polyp form. These include ''Sarsia'', '' Polyorchis'' and '' Cladonema''. Families According to the World Register of Marine Species, the following families are found in this suborder : * Asyncorynidae Kramp, 1949 * Cladocorynidae Allman, 1872 * Cladonematidae Gegenbaur, 1857 * Corynidae Johnston, 1836 * Halimedusidae Arai & Brinckmann-Voss, 1980 * Hydrocorynidae Rees, 1957 *Milleporidae Fleming, 1828 * Moerisiidae Poche, 1914 * Pennariidae McCrady, 1859 *Porpitidae Goldfuss, 1818 * Pseudosolanderiidae Bouillo ...

Porpitidae
The chondrophores or porpitids are a small group of hydrozoans in the family Porpitidae. Though it derives from an outdated name for this lineage (see below), some still find the term "chondrophore" useful as a synonym to "porpitid" in discussions of the two genera contained therein. They all live at the surface of the open ocean, and are colonies of carnivorous, free-floating hydroids whose role in the plankton community is similar to that of pelagic jellyfish. The chondrophores look like a single organism but are actually colonial animals, made up of orderly cooperatives of polyps living under specialized sail-structures. The most familiar members of the family Porpitidae are the blue button (''Porpita porpita'') and the by-the-wind sailor (''Velella velella''). Description The tiny individual animals are specialized to perform specific tasks; some form the central gas-filled disc (which is a golden brown colour and hardened by chitinous material) essential to keeping the ...

Rosalindidae
Rosalindidae is a family of cnidarians belonging to the order Anthoathecata. Description Rosalindidae are hydrozoans that are characterized by their ability to form colonies of polyps and attach to various surfaces, such as seaweed and shells, in the ocean. Rosalindidae are classified as invertebrates. They are considered epibionts, which rely on other invertebrates to live and develop. Although hydroids like Rosalindidae typically live on hard substrates and among coral rubble, as well as colonize scleractinia, researchers have found Rosalindidae growing on larger animal hosts such as ''Cladocarpus paradiseus'' hydroids. Rosalindidae form monomorphic colonies (monomorphism) in contrast to the polymorphic colonies (polymorphism) that characterize other hydrozoan families. Rosalindidae make up the order Anthoathecata - a hydroid group generally known for its fragility due to the lack of a perisarc to protect its gonophores and hydranths. However, colonies of polyps that fall un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cladonematidae
Cladonematidae is a small family of anthomedusan hydrozoans. They have stolonal hydroid colonies, and their medusae are benthic and can crawl across the sediment; in many species they have lost the ability to swim however.Schuchert 009/ref> Several members of this lineage were formerly considered a separate family Eleutheriidae.WoRMS Description The hydranths have a circular mouth surrounded by a single whorl of adhesive tentacles which each bear a little knob at the tip; in some Cladonematidae an aboral whorl of thread-like unknobbed tentacles is also present. They have a preoral chamber formed by epidermal gland cells. The medusae bud off at the base of the hydrants, though where aboral tentacle are present these are located between the stolons and the budding sites. Cladonematidae medusae have a various extend of nematocysts around their umbrellar margin, varying between a continuous dense ring to none at all among the species.
