The cauliflower soft coral (Eunephthya thyrsoidea) is a species of colonial soft coral in the family Nephtheidae. [3]
Cauliflower soft corals grow in colonies of up to 30 centimeters in height. The polyps are 0.2 cm in diameter. It grows as a large whitish colony with side branches ending in bunches of grey- or brown-tinged polyps. [4]
This species is known from the Cape Peninsula to northern KwaZulu-Natal off the South African coast, and lives from 10 to 240m under water.
This species is often found on vertical rockfaces and when not feeding it contracts tightly, and its resemblance to a cauliflower is striking. It is fed upon by the walking anemone, Preactis millardae. [4]
Corals are colonial marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.
Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals and soft corals. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton. The basic unit of the adult is the polyp; this consists of a cylindrical column topped by a disc with a central mouth surrounded by tentacles. Sea anemones are mostly solitary, but the majority of corals are colonial, being formed by the budding of new polyps from an original, founding individual. Colonies are strengthened by calcium carbonate and other materials and take various massive, plate-like, bushy or leafy forms.
Fire corals (Millepora) are a genus of colonial marine organisms that exhibit physical characteristics similar to that of coral. The name coral is somewhat misleading, as fire corals are not true corals but are instead more closely related to Hydra and other hydrozoans, making them hydrocorals. They make up the only genus in the monotypic family Milleporidae.
The soft coral nudibranch, Tritonia sp. 1, as designated by Gosliner, 1987, is a species of small sea slug, a dendronotid nudibranch. It is a marine gastropod mollusc in the family Tritoniidae. As of November 2009, it was undescribed by science.
The multicoloured sea fan is a species of gorgonian sea fan in the family Melithaeidae.
Nephtheidae is a family of soft corals in the phylum Cnidaria. Members of this family are known as carnation corals, tree corals or colt soft corals. They are very attractive and show a wide range of rich and pastel colours including reds, pinks, yellows and purples. They are popular with reef aquarium hobbyists.
Balanophyllia bonaespei is a species of solitary cup coral, a stony coral in the family Dendrophylliidae. It is an azooxanthellate species that does not contain symbiotic dinoflagellates in its tissues as most corals do.
The purple soft coral is a species of colonial soft coral in the family Alcyoniidae.
The Valdivian soft coral is a species of colonial leathery or soft coral in the family Alcyoniidae.
The variable soft coral is a species of colonial soft coral in the family Alcyoniidae.
The sun-burst soft coral is a species of colonial soft corals in the family Malacacanthidae. It is the only species known in the genus Malacacanthus.
Capnella is a genus of soft corals in the family Nephtheidae. They are also commonly known as Kenya tree corals.
The feathery sea pen is a species of sea pen in the family Virgulariidae.
The gorgonian twig coral is a species of gorgonian sea fan in the family Anthothelidae.
The nippled sea fanEunicella microthela previously known by the junior synonym Eunicella papillosa, is a species of gorgonian sea fan in the family Gorgoniidae.
The sinuous sea fan is a species of gorgonian sea fan in the family Gorgoniidae.
The palmate sea fan is a species of gorgonian sea fan in the family Gorgoniidae.
Stylaster nobilis, the noble coral, is a branching colonial hydroid in the family Stylasteridae.
Pocillopora verrucosa, commonly known as cauliflower coral, rasp coral, or knob-horned coral, is a species of stony coral in the family Pocilloporidae. It is native to tropical and subtropical parts of the Indian and Pacific Oceans.
Pseudonephthea is a genus of corals containing the only species Pseudonephthea liltvedi, or the stalked cauliflower soft coral. It is a cnidarian that is endemic to the coast of South Africa.
