Bougainvillia Principis
''Bougainvillia'' is a genus of hydroid (zoology), hydroids in the Family (biology), family Bougainvilliidae in the Class (biology), 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 polyp (zoology), polyps on the hulls of ships.

Bougainvillia Muscus
''Bougainvillia muscus'' is a marine invertebrate, a species of hydroid in the suborder Anthomedusae. Taxonomy In 1844, van Beneden named the hydroid form of this species as ''Eudendrium ramosum''. Strethill Wright showed that it did not belong in the genus ''Eudendrium'' and placed it in ''Atractylis''. Later Allman placed it in ''Bougainvillia'' on the basis of its similarity to ''Bougainvillia britannica''. Strethill Wright reared some medusae to maturity and decided that the species was in fact ''Bougainvillia britannica''. However, confusion remained because the three hydroid forms, ''B. ramosa'', ''B. fruticosa'' and ''B. muscus'' were so similar. The name ''B. ramosa'' has been widely used for this species in the past but ''B. muscus'' is now the accepted name. Description ''B. muscus'' is a colonial hydroid forming irregular, straggling branched bushes. The individual polyps have two rings of tentacles pointing alternately upwards and downwards. The colony may grow to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
