Oculina Varicosa
''Oculina varicosa'', or the ivory bush coral, is a scleractinian deep-water coral primarily found at depths of 70-100m, and ranges from Bermuda and Cape Hatteras to the Gulf of Mexico and the Caribbean. ''Oculina varicosa'' flourishes at the Oculina Bank off the east coast of Florida, where coral thickets house a variety of marine organisms. The U.S. National Marine Fisheries Service considers ''Oculina'' a genus of concern, due to the threat of rapid ocean warming. Species of concern are those species about which the U.S. Government's National Oceanic and Atmospheric Administration (NOAA), National Marine Fisheries Service, has some concerns regarding status and threats, but for which insufficient information is available to indicate a need to list the species under the U.S. Endangered Species Act (ESA). While ''Oculina'' is considered a more robust genus in comparison to tropical corals, rising ocean temperatures continue to threaten coral health across the planet. Specie ...

Oculina Arbuscula
''Oculina arbuscula'' is a branching temperate coral found along the east coast of the United States from Florida to North Carolina. It has a facultative symbiosis with microalgae of the family Symbiodiniaceae. Unlike tropical corals, ''O. arbuscula'' can survive without its algal endosymbionts by switching to a predominantly heterotrophic feeding strategy. Symbiotic colonies are typically found in shallower waters due to light availability, whereas aposymbiotic (without symbionts) or mixed colonies are found as deep as 200m. The ability of ''O. arbuscula'' to exist in different symbiotic states makes it a good model system for studying the cnidarian-dinoflagellate symbiosis. Morphology ''O. arbuscula'' forms colonies up to 0.5 meters in diameter with relatively short stubby branches. Symbiotic colonies, depending on symbiont density, range from light to dark brown in color, whereas aposymbiotic colonies are white. Oftentimes colonies with mixed symbiotic states will be seen, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oculina Diffusa
''Oculina diffusa'', commonly known as the diffuse ivory bush coral or ivory tree coral, is found in the eastern Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. It is found in shallow water, usually down to deep but occasionally as deep as . Its colonies are dense and have a yellow-brown color. It favours areas with high amounts of sedimentation. Physical appearance Colonies of ''Oculina diffusa'' are usually about in diameter and have twisting narrow branches less than half an inch in diameter. Colonies have been recorded at temperatures ranging from 13–31 degrees Celsius. Food ''Oculina diffusa'' normally eat plankton Plankton are the diverse collection of organisms found in water (or air) that are unable to propel themselves against a current (or wind).

Zooxanthella
Zooxanthellae is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs. Most known zooxanthellae are in the genus ''Symbiodinium'', but some are known from the genus ''Amphidinium'', and other taxa, as yet unidentified, may have similar endosymbiont affinities. The true ''Zooxanthella'' K.brandt is a mutualist of the radiolarian ''Collozoum inerme'' (Joh.Müll., 1856) and systematically placed in Peridiniales. Another group of unicellular eukaryotes that partake in similar endosymbiotic relationships in both marine and freshwater habitats are green algae zoochlorellae. Zooxanthellae are photosynthetic organisms, which contain chlorophyll a and chlorophyll c, as well as the dinoflagellate pigments peridinin and diadinoxanthin. These provide the yellowish and brownish colours typical of many of the host species. During the day, they provide their host with t ...
