Corallites
Corallites of a larger size respond to this dominance by impaired development of skeletal elements in the mergence zone, apparently connected with damage and growth of the outer wall. In the second section (1.5 mm from the previous one, Fig. 3b), the mutual influence of the two merged corallites seems to be almost balanced. The …Acropora humilis, also known as finger coral, is a species of acroporid coral found in the Gulf of Aden, the Red Sea, the northern and southwestern Indian Ocean, Australia, the central Indo-Pacific, Japan, southeast Asia, the East China Sea, the central and western Pacific Ocean, the Johnston Atoll and the northwestern Hawaiian Islands.It also occurs in the Raja Ampat …

Corallites are 3-4.5 millimetres diameter, with numerous septa tightly compacted giving a smooth surface. Septa are uniformly separated and reduce in number from the wall to the columella without forming many fan-like fusions. Colour: Usually light reddish-brown. Similar Species: Corallites are larger than any other Siderastrea . The pink species is winning at this time - notice the new white corallites overgrowing the brownish species. (SA images) Reef building coral species may compete with each other for space. These competitions, when two coral heads meet, may go on for hundreds of years with the advantage changing as conditions change. Over time, the reef itself ...Corallites of a larger size respond to this dominance by impaired development of skeletal elements in the mergence zone, apparently connected with damage and growth of the outer wall.

Even greater levels of integration are found among thamnasteroid colonies. These share tentacles, and septa on one corallite are confluent with those of adjacent ones. In meandroid taxa, or “brain corals”, corallites are organized into deep, sinuous valleys ...Due to the simple morphology of internal characters like the polygonal corallites, pores predominantly located in corners, variable thickness of corallite wall and septal development, and by the similar size of corallites, this species is easily confused with P.Corallites are 3-4.5 millimetres diameter, with numerous septa tightly compacted giving a smooth surface. Septa are uniformly separated and reduce in number from the wall to the columella without forming many fan-like fusions. Colour: Usually light reddish-brown. Similar Species: Corallites are larger than any other Siderastrea . Orange pipe coral is an encrusting coral that can become massive and strongly convex. The corallites are covered with porous tissue with a vermicular appearance. The calyx has a diameter of 0.31–0.39 and a depth of 0.20–0.31. Its polyp’s tentacles are bright yellow-orange, while the coenosteum and the center of the polyps are deeper oranges. Corallites of a larger size respond to this dominance by impaired development of skeletal elements in the mergence zone, apparently connected with damage and growth of the outer wall.

In some chain corals, larger corallites (termed autocorallites or macrocorallites) connect with each other, and in others, larger corallites alternate with much thinner tubes and tissues (termed tubules, microcorrallites, and mesocorallites). A morphometrical method to quantify and characterize coral corallites using Richardson Plots and Kaye’s notion of fractal dimensions is presented. A Jurassic coral species (Aplosmilia spinosa) and five Recent coral species were compared using the Box-Counting Method. This method enables the characterization of their morphologies at …Radial corallites are of two sizes, usually in rows.

Underwater, the corallites of P. lutea are filled with skeletal elements, whereas the corallites of P. lobata appear to have fewer elements and thus look more open. Porites somaliensis has similar corallite characters.

They are long and slender, parallel-sided or irregularly cylindrical. Corallites are generally between 1·0 and 2·5 mm in width and in excess of 40 mm in length prior to the addition of new corallites (increase). Corallites: individual skeletal elements occupied by one polyp. These tend to be small in tabulate corals, and to lack complicated internal structures. Individual corallites are linked into a corallum shaped like a chain (cateniform). The shape of the corallite and the corallum are highly variable in corals. Septa: small or absent in tabulate ...
