  2. Skeletal eroding band - Wikipedia

    en.wikipedia.org/wiki/Skeletal_Eroding_Band

    Skeletal eroding band is visible as a black or dark gray band that slowly advances over corals, leaving a spotted region of dead coral in its wake. [1] The spotted area distinguishes skeletal eroding band from black band disease, [1] which also forms an advancing black band but leaves a completely white dead area behind it.

  3. Live rock - Wikipedia

    en.wikipedia.org/wiki/Live_rock

    Bleached coral skeletons, which can be inhabited by micro- and macro-organisms to form live rock. There are many different types of live rock. Each is named after the area from which it originated. A large amount of live rock comes from the Southern Pacific region, in areas such as Fiji, Tonga, and the Marshall Islands, as well as from the ...

    en.wikipedia.org/wiki/Electrified_reef

    Skeletons of dead coral and algae from the reef are then deposited and help grow beaches. [ 8 ] [ 9 ] [ dubious – discuss ] Because these reefs mimic the properties of natural reefs they solve some of the challenges they have in storm dissipation and their self-healing qualities helps structures survive extreme storms as long as the ...

  5. Marine biogenic calcification - Wikipedia

    en.wikipedia.org/wiki/Marine_biogenic_calcification

    The resulting structures, such as shells, skeletons, and coral reefs, function as protection, support, and shelter and create some of the most biodiverse habitats in the world. Marine biogenic calcifiers also play a key role in the biological carbon pump and the biogeochemical cycling of nutrients, alkalinity , and organic matter.

  6. Vital effects - Wikipedia

    en.wikipedia.org/wiki/Vital_effects

    Similar to foraminifera shells, the isotopic composition of coral skeletons is used to reconstruct past temperature, CO 2 concentrations, and pH. [6] [7] Vital effects arise from algal symbionts and biological responses to changes in conditions such as pH. Again, culture experiments are used to quantify vital effects and calibrate the use of ...

  7. Scleractinia - Wikipedia

    en.wikipedia.org/wiki/Scleractinia

    A rugose coral seems an unlikely common ancestor because these corals had calcite rather than aragonite skeletons, and the septa were arranged serially rather than cyclically. However, it may be that similarities of scleractinians to rugosans are due to a common non-skeletalized ancestor in the early Paleozoic.

  8. Halofolliculina corallasia - Wikipedia

    en.wikipedia.org/wiki/Halofolliculina_corallasia

    Halofolliculina corallasia is a species of heterotrich ciliates identified as a cause of the syndrome called skeletal eroding band (SEB). It is the first coral disease pathogen that is a protozoan as well as the first known to be a eukaryote; all others identified are bacteria. [1]

  9. Environmental issues with coral reefs - Wikipedia

    en.wikipedia.org/wiki/Environmental_issues_with...

    The increase mass coral dead zones is reinforced by the spread of coral diseases. Coral diseases can spread easily when there are high concentrations of sulfide and hypoxic conditions. Due to the loop of hypoxia and coral reef mortality, the fish and other marine life that inhabit the coral reefs have a change in behavioral in response to the ...
