Holaxonia
Holaxonia is a suborder of soft corals, a member of the phylum Cnidaria.Holaxonia World Register of Marine Species. Retrieved 2011-12-03. Members of this suborder are sometimes known as gorgonians and include the sea blades, the sea fans, the sea rods and the sea whips. These soft corals are colonial, sessile organisms and are generally tree-like in structure. They do not have a hard skeleton composed of calcium carbonate but have a firm but pliable, central axial skeleton composed of a fibrous called |
Alcyonacea
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kept in c ...

Gorgoniidae
Gorgoniidae is a family of soft corals, a member of the subclass Octocorallia in the phylum Cnidaria. Nearly all the genera and species are native to the east and west coasts of America. Characteristics Originally the members of the family Gorgoniidae included a much wider range of genera than it does now and was used for all of the horny Octocorallia. Now it is restricted to those species where the "calcareous spicules are less than 0.3 mm. in length, sculptured with regularly disposed girdles of complicated tubercles ('warts'), the anthocodiae are relatively unarmed, at most with but a few characteristically shaped flat rods en chevron beneath each tentacle, the horny axial cylinder is weakly loculated if at all, and is perforated by a relatively narrow, chambered central chord, and in which the branchlets are usually quite slender, with a thin cortex.''" The polyps are retractable and the stems have an axis of the protein gorgonin surrounding a narrow, hollow, cross-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plexauridae
Plexauridae is a family of marine colonial octocorals in the phylum Cnidaria. Members of this family are found in shallow tropical and subtropical seas. Many species contain symbiotic photosynthetic protists called zooxanthellae. Characteristics The Plexauridae have a branching colony form and many are known as sea rods or sea fans. The axial core of the coral skeleton is horny and hollow, and contains no sclerites. This is covered by a layer of tissue called coenenchyme in which is embedded calcareous sclerites. The sclerites are very varied in form in the Plexauridae, and examination of their morphology is helpful in identifying the different species. The calyces in which the polyps sit are strengthened by further sclerites and have eight fine dividing walls called septa The Southeastern Pennsylvania Transportation Authority (SEPTA) is a regional public transportation authority that operates bus, rapid transit, commuter rail, light rail, and electric trolleybus servic ...
