Gersemia Rubiformis
''Gersemia rubiformis'', commonly known as the sea strawberry, is a species of soft coral in the family Nephtheidae. It is found in the northwest Atlantic and the northeast Pacific Oceans. Description ''Gersemia rubiformis'' is a colonial coral that grows in the form of knobbly clumps. The colonies are erect and branch from one main stalk. The polyps are concentrated near the ends of the narrower terminal branches and are non-retractile in their calyces. The branches are not rigid but are stiffened by the presence of sclerites, and can sway gently in the current. The sclerites are red, some being irregular and shaped like miniature capstans. ''Gersemia rubiformis'' does not contain the symbiotic alga zooxanthella. Distribution ''Gersemia rubiformis'' is found in polar to temperate regions of the Arctic Ocean and the north west Atlantic Ocean from the coasts of Canada south to Cape Hatteras in North Carolina.

Gersemia Liltvedi
''Pseudonephthea'' is a genus of corals containing the only species ''Pseudonephthea liltvedi'', or the stalked cauliflower soft coral. It is a cnidarian that is endemic to the coast of South Africa. Description Colonies, which may consist of several stems, rise from a single base. The colonies range between and in size. They form erect, cauliflower-like forms with the polyps closely clustered at the ends of short, narrow branches. The bundles of polyps are supported by cup-like structures and do not have. The colonies are variable in colour and usually range from white ir pale beige to pink and orange. They may look similar to species belonging to ''Eunephthya''. ''Eunephthya'' species, however, have branches of equal width (opposed to a range of ranch thicknesses found in ''Pseudonephthea liltvedi).'' Distribution and habitat This species is endemic to the Benguela region off the west coast of South Africa. They lack zooxanthellae, which allows them to grow in deeper ...

Gersemia Juliepackardae
''Gersemia juliepackardae'' is a species of soft coral in the family Nephtheidae. It is found in the northeast Pacific Ocean, on seamounts or on the deep ocean bed. The coral is named in honour of Julie Packard, the executive director of the Monterey Bay Aquarium, for "her dedication to ocean stewardship and conservation, and for elevating public awareness about the ocean environment." Description Colonies of ''Gersemia juliepackardae'' have an upright main stem and are attached to the substrate by a holdfast. The stalk of the holotype is tall with a width of at the base. Lateral branches start just above the holdfast and are borne mostly in two opposite rows. Each of these lateral branches develop several secondary branchlets near the tip. The non-retractable polyps are tubular in shape and are mostly on the secondary branches. The eight tentacles on each polyp can be retracted into the polyp body. The polyps are about long, the basal part being while and the tentacular part ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gersemia Fruticosa
''Gersemia fruticosa'' is a species of soft coral in the family Nephtheidae. It is a deep sea species with a boreal distribution and is found in the northwest Atlantic Ocean, from off the coast of Delaware northward to Baffin Bay and the Davis Strait, and also in the northeast Atlantic Ocean in the Barents Sea. Biology Little is known of the reproduction of deep sea corals, especially soft corals, because observation is so difficult at the depths at which they live. ''Gersemia fruticosa'' was brought to the surface and maintained in the laboratory under flow-through conditions. Planula larvae were released between April and June, at the time of year when the greatest quantity of phytoplankton was present in the water. The larvae were between long and settled and underwent metamorphosis between 3 and 70 days after release. Three months later, the new primary polyps were up to high with a stalk diameter of . These juveniles were maintained for over a year but no budding took plac ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
