Spur and groove formations are a geomorphic feature of many coral reefs. They are ridges of reef formed by coral ("spurs") separated by channels ("grooves") which often have sediment or rubble bed. Spur and groove formations vary in their size and distribution worldwide but are a common feature on many forereefs of fringing reefs , barrier ...
Canton Island typifies the isolated coral atolls dotting the Pacific Ocean. The Structure and Distribution of Coral Reefs, Being the first part of the geology of the voyage of the Beagle, under the command of Capt. Fitzroy, R.N. during the years 1832 to 1836, was published in 1842 as Charles Darwin's first monograph, and set out his theory of the formation of coral reefs and atolls.
It also produces and releases certain minerals which benefit the habitat in which it inhabits. It is found on reef flats and the edges of the reef varying in depth. The moss can be anywhere from 1–17 meters deep. [4] It can also loosely attach itself to the coral. They can form large unattached fragments that can form a mat like structure.
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. [1] Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and ...
It includes all of the stony corals, most of which are colonial and reef-forming, as well as all sea anemones, and zoanthids, arranged within five extant orders. [2] The hexacorallia are distinguished from another class of Anthozoa, Octocorallia , in having six or fewer axes of symmetry in their body structure; the tentacles are simple and ...
Pocillopora capitata, commonly known as the Cauliflower coral, is a principal hermatypic (or reef-building) coral found in the Eastern Tropical Pacific. [ 3 ] [ 4 ] [ 5 ] P. capitata is a colonial species of stony coral of the class Anthozoa , the order Scleractinia , and the family Pocilloporidae . [ 6 ]
Porites is a genus of stony coral; they are small polyp stony (SPS) corals. (Also referred to as finger coral or hump coral) They are characterised by a finger-like morphology. Members of this genus have widely spaced calices, a well-developed wall reticulum and are bilaterally symmetrical.
Acropora is a genus of small polyp stony coral in the phylum Cnidaria. [3] Some of its species are known as table coral, elkhorn coral, and staghorn coral. Over 149 species are described. [4] Acropora species are some of the major reef corals responsible for building the immense calcium carbonate substructure that supports the thin living skin ...
