Perophora Clavata
''Perophora'' is a tunicate, sea squirt genus in the family Perophoridae. Most species are found in shallow warm water but a few are found in higher latitudes. A colony consists of a number of zooids which bud off from a long slender stolon. Characteristics A ''Perophora'' colony consists of a system of stolons from which individual zooids arise at intervals. Each zooid has four or five rows of stigmata in the wall of the atrium, the one exception being ''Perophora multistigmata'' which has eight rows. In some cases, the five-rowed species have some stigmata extending over the first and second rows indicating that the primary number of rows is four. In ''Ecteinascidia'', the only other genus in the family, there are always eight or more rows of stigmata, usually twelve to twenty rows. Other distinguishing characteristics are that ''Perophora'' has a horizontal gut loop with a short rectum and a testis with usually one, but up to four lobes, situated in the gut loop. In ''Ecteinasc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perophora Viridis
''Perophora viridis'', the honeysuckle tunicate, is a species of colonial sea squirt in the genus '' Perophora'' found in the tropical western Atlantic Ocean. Description ''Perophora viridis'' is a colonial sea squirt with the individual zooids united by a stolon or stem but spaced widely apart. The stolon meanders along the surface of the substrate forming a mat. The base of each zooid is attached to the stolon and its body resembles a small barrel, with an opening at the top and another at the side, each opening raised on a rim. These are the buccal siphon through which water flows into the body of the animal and the atrial siphon through which it is expelled. A large pharynx occupies much of the interior and the surrounding muscular body wall is known as the mantle. The pharynx opens into a horizontally aligned gut which loops around to terminate near the atrial siphon. There are four bands of "stigmata" on the inside of the mantle, a fact that this species has in common with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perophora Regina
''Perophora regina'' is a species of colonial sea squirt in the genus '' Perophora''. It is native to the tropical western Atlantic Ocean where it is found growing on mangrove roots on the Belize Barrier Reef. Description A colony of ''Perophora regina'' consists of a mat of slender, branching stolons, with short-stalked zooids growing at intervals. The zooids are so crowded together in mature colonies that the surface of the colony appears smooth. The zooids are long and on each there is a yellow neural gland between the siphons with a distinctive white spot on either side of this. Like ''Perophora viridis'', the zooids have four rows of stigmata and the muscles in the mantle wall are predominantly longitudinal. This tunicate broods its embryos in a pouch at the lower right side of the atrium. Distribution and habitat ''Perophora regina'' is found in scattered locations on the Belize Barrier Reef where it is found growing profusely on mangrove roots in fast moving water. It is ...

Perophora Multiclathrata
''Perophora multiclathrata'' is a species of colonial sea squirt in the genus '' Perophora''. It is native to the tropical Indo-Pacific and the western Atlantic Ocean. Description A colony of ''Perophora multiclathrata'' consists of slender, branching stolons, with unstalked zooid A zooid or zoöid is an animal that is part of a colonial animal. This lifestyle has been adopted by animals from separate unrelated taxa. Zooids are multicellular; their structure is similar to that of other solitary animals. The zooids can ...s growing at intervals. Each zooid is long and has about twenty tentacles surrounding the buccal siphon, alternately long and short. The pharynx has five rows of stigmata, some of which extend from the first row into the second. The musculature in the atrial wall is distinctive with horizontal and radial elements and a circular muscle fibre surrounding the base of the atrial siphon allowing the atrium to become pouched and the atrial siphon to be pulled ...
