Bougainvilliidae
Bougainvilliidae is a family of marine hydroids in the class Hydrozoa. Members of the family are found worldwide. There are sixteen accepted genera and about ninety-three species. Description Hydroids in this family can be solitary or colonial. When colonial, the hydranths or hydroid polyps are either linked by stolons or are branched. The hydranths have one or more whorls of fine tentacles. The gonophores are free-living medusae or are fixed sporosacs. The medusae are bell-shaped with a circular mouth and branched oral tentacles inserted above the rim of the mouth, ending in clusters of nematocysts.

Nemopsis Bachei
''Nemopsis bachei'' is a species of relatively small gelatinous zooplankton hydrozoa found in both marine and estuarine environments. This particular species was first found and described by Louis Agassiz in 1849 from samples that were taken from the coast of Massachusetts. It was also noted and described in 1857 by another name off the coast of South Carolina.Moore, D.R. “Occurrence and distribution of Nemopsis bachei Agassiz (Hydrozoa) in the Northern Gulf of Mexico”. ''Bulletin of Marine Science of the Gulf and Caribbean'' (1962) As part of the phylum Cnidaria they are mainly gelatinous with their most identifying characteristic being the gonads which, viewed from above, look like an X and then continue down the sides lining up with the radial canals. As a part of the zooplankton, it is incapable of sustained horizontal movement and relies on its tentacles to encounter and capture smaller organisms for food (feeds mainly on copepedites, selecting against naupilar stages).Pu ...

Bougainvillia
''Bougainvillia'' is a genus of hydroids in the family Bougainvilliidae in the class Hydrazoa. Members of the genus are characterised by having the marginal tentacles of their medusae arranged in four bundles. Some species are solitary and others are colonial but all are filter feeders. They are found in the Southern Ocean, having a circumpolar distribution, but some species also occur in the Northern Hemisphere, possibly travelling there as polyps on the hulls of ships.

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.

Polyp (zoology)
A polyp in zoology is one of two forms found in the phylum Cnidaria, the other being the medusa. Polyps are roughly cylindrical in shape and elongated at the axis of the vase-shaped body. In solitary polyps, the aboral (opposite to oral) end is attached to the substrate by means of a disc-like holdfast called a pedal disc, while in colonies of polyps it is connected to other polyps, either directly or indirectly. The oral end contains the mouth, and is surrounded by a circlet of tentacles. Classes In the class Anthozoa, comprising the sea anemones and corals, the individual is always a polyp; in the class Hydrozoa, however, the individual may be either a polyp or a medusa, with most species undergoing a life cycle with both a polyp stage and a medusa stage. In class Scyphozoa, the medusa stage is dominant, and the polyp stage may or may not be present, depending on the family. In those scyphozoans that have the larval planula metamorphose into a polyp, the polyp, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
