Acropora cytherea. (Dana, 1846) Characters: Colonies are wide flat tables which are usually thin and finely structured. May become thick and robust in turbulent environments. Fine upward projecting branchlets have exsert axial corallites. Radial corallites are short, with open calices. Tentacles are frequently extended during the day.New corallites were initiated at the summit of each bump and grew upwards and outwards. Thus, growth of colonies resulted in corallites becoming increasingly displaced from the summit of a bump.22 dic 2017 ... Until recently, all three Orbicella species were classified as Montastrea.

Coral is secreted by some coral forming actinozoa. The skeleton of a solitary polyp is known as the corallite (Fig. 12.38) and many corallites combine to form the skeletal mass. The skeleton as a whole is known as the corallum. The structure of a corallum will be clear from the detailed structural organisa­tion of a single corallite.Most of the reef-building Acropora corals around Okinawa Island spawn in May and/or June. We found that two morphotypes of Acropora divaricata spawned in August and/or September. The “robust” and “slender” morphotypes differed in branch width and in the diameter of axial corallites. Histological analyses showed that the onset of gamete …Fine upward projecting branchlets. Tentacles often extended during day. Colour: Pale cream, brown or blue. Axial Corallites: Exsert.

Corallites cylindrical and usually stout, corallites do not anastomose, but branches do. Septotheca costate and granular.The axial corallites are tubular, rounded and slightly prominent.

The corallites of some species were connected by fine tubules forming a three-dimensional structure. Where corallites were in close contact, tabulae were usually formed. Where corallites were separated, external horizontal plates (dissepiments) also occurred.

For some species of coral, the corallites are fused together to form elongated ridges and valleys. Many species with fused corallites are commonly called brain corals because of their appearance, whereas many species with discrete corallites are commonly referred to as star corals. Apr 27, 2020 · This discovery was reported by Copper (1985), who reported that individual corallites typically had 12 tentacles, though some had 11 or 13. The discovery of these polyps also confirmed that Tabulata are indeed Cnidarians, rejecting the hypothesis of some earlier workers that this group belonged with the sponges.

Axial corallites are long, tubular, and upright, becoming horizontal towards the plate margins where they are similar to radial corallites. Note the long, dominant, numerous, tubular, axial corallites and compare them with the small, incipient, appressed, radial corallites. Montipora verrucosa. Characters: Colonies are encrusting, submassive, form columns, or are laminar. The surface is uniformly covered with large rounded verrucae. Corallites are immersed between the verrucae.
