Acropora palmata - Corals of the World.

White Band type II in Acropora cervicornis. There are two etiologies of white band disease, type I and type II. In type I, tissue destruction is associated with the moving front of the band. In type II, there is at times a bleached zone between the area of tissue degradation and the moving front.

Colour: Many colours, but most usually cream, brown, purple or blue (which may photograph purple) with blue or cream tips. Similar Species: Acropora gemmifera, which has small axial corallites and radial corallites increasing in length down branches. See also A.

Acropora palmata succeeds best at depth range of 3 m to 5 m. From the begining of the reef history in the Gulf of Mannar, the reefs were confined only in the shallow. The classification types and amount of damage caused by micro and macro borers are studied through thin section and SEM studies.

Keeping Acropora Corals Beautiful home reefs can be either a simple reef with hardier, less demanding animals, or a more complex reef with higher maintenance specimens. Stony corals are more demanding and take a more dedicated effort.

Maximum depth from Ref. 116012. Zooxanthellate (Ref. 116012).Found in shallow areas of high wave action, especially reef crests (Ref. 415) and submerged reef tops (Ref. 86439).Hermaphroditic (Ref. 113712).Mature gametes are shed into the coelenteron and spawned through the mouth.

In this photograph, we can see the branching elkhorn coral Acropora palmata (upper left), with arms showing strong orientation into an oscillatory current between left and right. In the right foreground is the mound-shaped coral Montastrea annularis. It is of great interest that such differently shaped corals can occur side by side.

The staghorn coral (Acropora cervicornis) is a branching, stony coral with cylindrical branches ranging from a few centimetres to over two metres in length and height. It occurs in back reef and fore reef environments from 0 to 30 m (0 to 98 ft) depth. The upper limit is defined by wave forces, and the lower limit is controlled by suspended sediments and light availability.

Another unique species of Acropora is the Palmata or more commonly referred to as the Elkhorn, it has very thick-plated branches. It is one of the largest growing colonies of all Acropora. Acropora comes in such a huge range of shapes and sizes which is what makes them so unique.

An Optical Remote-Sensing Evaluation of the Status of Acropora palmata in Vieques, Puerto Rico. The images were pre-processed to minimize noise and unsupervised classification was used to detect areas colonized by seagrass.. Their decline was to such an extent that both Acropora palmata and A. cervicornis were placed on the Candidate.

None of the three important keystone species (Acropora palmata, Acropora cervicornis, and Diadema antillarum) have shown much recovery over decadal time scales. In addition, continuing coral mortality from periodic acute events such as hurricanes, disease outbreaks, and bleaching events from ocean warming have added to the poor state of Caribbean coral populations and yielded a remnant coral.

The branching coral Acropora palmata is a foundation species of Caribbean reefs that has been decimated in recent decades by anthropogenic and natural stressors. Declines in population density and genotypic diversity likely reduce successful sexual reproduction in this self-incompatible hermaphrodite and might impede recovery.

Definition noun, plural: elkhorn corals A coral species that resembles the horns of an elk Supplement An elkhorn coral is a stony coral species. Its name is derived from its resemblance to the horns (antlers) of an elk.It is highly branched and structurally complex.
