Corallimorpharia
Corallimorpharia is an order of marine cnidarians closely related to stony or reef building corals (Scleractinia). They occur in both temperate and tropical climates, although they are mostly tropical. Temperate forms tend to be very robust, with wide and long columns, whereas tropical forms tend to have very short columns with a wide oral disc and very short tentacles. The tentacles are usually arranged in rows radiating from the mouth. Many species occur together in large groups, although there are recorded instances of individuals. In many respects, they resemble the stony corals, except for the absence of a stony skeleton. Morphological and molecular evidence suggests that they are very closely related to stony corals. Corallimorpharians occur in a wide range of marine habitats, and can be associated with phase shifts in coral reef ecosystems that result in a change from a hard-coral dominated reef to a soft-coral dominated one. They have been observed to overgrow reefs in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ricordea Yuma
''Ricordea yuma'' is a species of coral in the family Ricordeidae, order Corallimorpharia; This order of corals do not produce the distinctive calcification of the closely related Scleractinian, or reef building corals. ''Ricordea yuma'' are found on the sea floor in relatively shallow, tropical or subtropical ocean environments. Distinctive features include a large mouth disk that takes up most of the organism, and brightly colored tentacles. ''Ricordea yuma'' can reproduce both sexually, and asexually by budding a new coral with replicated elements from the mother coral. This may be one mechanism of how they are able to spread and overtake areas rapidly; They have been observed being competitively successful at monopolizing areas by excluding reef-building coral species, after a disturbance in the substrate. Anatomy and Morphology ''Ricordea yuma'' is a corallimorpharian species, often called “naked” or “false” corals because they lack the distinctive calcification ...

Corynactis Californica
''Corynactis californica'' is a brightly colored colonial anthozoan corallimorph. Unlike the Atlantic true sea anemone, '' Actinia fragacea'', that bears the same common name, strawberry anemone, this species is a member of the order Corallimorpharia, and is the only member found in the North American West Coast. Other common names include club-tipped anemone and strawberry corallimorpharian. The anemone can live up to at least 50 meters deep on vertical rock walls, and at the bottom of kelp forests. It is known to carpet the bottom of some areas, like Campbell River in British Columbia, and Monterey Bay in California. The strawberry anemone grows no larger than 2.5 centimeters. The anemone can be red, pink, purple, brown, yellow, or completely white. They possess tentacles that are white or transparent with bulbous tips. The strawberry anemone resembles sea anemones in that they lack a calcareous skeleton, but are closer related to stony corals in that they lack basilar muscle ...

Actinodiscus
'' Discosoma nummiforme'' ''Discosoma'' is a genus of cnidarians in the order Corallimorpharia. Common names for the genus include mushroom anemone, disc anemone and elephant ear mushroom.Sprung, JAquarium Invertebrates: Mushrooms, Elephants Ears, And False Corals: A Review Of The Corallimorpharia.''Advanced Aquarist'' Volume 1. October 2002. Most species are disc-shaped and produce large amounts of mucus. There are a great variety of colors, including metallic and fluorescent shades and striped and spotted patterns. ''Discosoma'' gather food particles from the water. Some species absorb nutrients produced by zooxanthellae, photosynthetic dinoflagellates living in their tissues in a symbiotic relationship.

Paracorynactis Hoplites
''Paracorynactis'' is a genus of corallimorphs from the western Indo-West Pacific. They are specialized predators of echinoderms, and are notable for preying on the destructive crown-of-thorns starfish ('' Acanthaster planci'') among others. The genus is monotypic with the single species, ''Paracorynactis hoplites''. Taxonomy ''Paracorynactis hoplites'' is the only species classified under the genus ''Paracorynactis''. It belongs to the family Corallimorphidae of the corralimorph order Corallimorpharia. It was first described as ''Corynactis hoplites'' by the British biologists Alfred Cort Haddon and Alice M. Shackleton in 1893. In 1980, it was transferred by the Dutch marine biologist Jacobus Cornelis den Hartog to the newly created genus '' Pseudocorynactis''. In 2010, Ocaña ''et al.'' noted the difference in tentacle development between this species and other members of the family Corallimorphidae. It was again transferred to a new genus, ''Paracorynactis''. Description ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudocorynactis
''Corynactis'' is a genus of colonial anthozoans similar in appearance to sea anemones and in body format to scleractinian stony corals. These animals are cnidarians in the family Corallimorphidae. Large unidentified polyps of this genus feed on the crown-of-thorns seastar '' Acanthaster planci'' and may help control the crown-of-thorns population. Species Species so far described in this genus include: *'' Corynactis annulata'' Verrill, 1867 *'' Corynactis australis'' Haddon & Duerden, 1896 *'' Corynactis caboverdensis'' den Hartog, Ocaña & Brito, 1993 *''Corynactis californica'' Carlgren, 1936 *'' Corynactis caribbeorum'' den Hartog, 1980 *'' Corynactis carnea'' Studer, 1879 *'' Corynactis chilensis'' Carlgren, 1941 *'' Corynactis delawarei'' Widersten, 1976 *'' Corynactis denhartogi'' Ocaña, 2003 *'' Corynactis denticulosa'' Le Sueur, 1817 *'' Corynactis globulifera'' Hemprich & Ehrenberg in Ehrenberg, 1834 *'' Corynactis parvula'' Duchassaing & Michelotti, 1860 *'' Corynact ...

Hexacorallia
Hexacorallia is a class of Anthozoa comprising approximately 4,300 species of aquatic organisms formed of polyps, generally with 6-fold symmetry. 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. 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 unbranched and normally number more than eight. These organisms are formed of individual soft polyps which in some species live in colonies and can secrete a calcite skeleton. As with all Cnidarians, these organisms have a complex life cycle including a motile planktonic phase and a later characteristic sessile phase. Hexacorallia also include the significant extinct order of rugose corals. Phylogeny Hexacorallia is considered to be monophyletic, that is all contained species are descended from a co ...
