Renilla is a genus of sea pen. It is the only genus within the monotypic family Renillidae. Sea pansy is a common name for species in this genus.
The following species are recognized: [1]
Illán de Vacas is a town in the province of Toledo, in Castile–La Mancha, Spain. The surface area of the municipality is 9 km2, it has a total population of 3 inhabitants, making it the least populated municipality in Spain.
Liolaemus is a genus of iguanian lizards, containing many species, all of which are endemic to South America.
Limonium is a genus of about 600 flowering plant species. Members are also known as sea-lavender, statice, caspia or marsh-rosemary. Despite their common names, species are not related to the lavenders or to rosemary. They are instead in Plumbaginaceae, the plumbago or leadwort family. The generic name is from the Latin līmōnion, used by Pliny for a wild plant and is ultimately derived from the Ancient Greek leimon.
Renilla reniformis, the sea pansy, is a species of soft coral in the family Renillidae. It is native to warm continental shelf waters of the Western Hemisphere. It is frequently found washed ashore on North East Florida beaches following northeasterly winds or rough surf conditions. It also can often be found living intertidally completely buried in the sand. Its predator is the striped sea slug, Armina tigrina.
A calcium channel is an ion channel which shows selective permeability to calcium ions. It is sometimes synonymous with voltage-gated calcium channel, which are a type of calcium channel regulated by changes in membrane potential. Some calcium channels are regulated by the binding of a ligand. Other calcium channels can also be regulated by both voltage and ligands to provide precise control over ion flow. Some cation channels allow calcium as well as other cations to pass through the membrane.
Deania is a genus of long-snouted, deepwater dogfish sharks in the family Centrophoridae.
Octocorallia is a class of Anthozoa comprising over 3,000 species of marine organisms formed of colonial polyps with 8-fold symmetry. It includes the blue coral, soft corals, sea pens, and gorgonians within three orders: Alcyonacea, Helioporacea, and Pennatulacea. These organisms have an internal skeleton secreted by mesoglea and polyps with eight tentacles and eight mesentaries. As with all cnidarians these organisms have a complex life cycle including a motile phase when they are considered plankton and later characteristic sessile phase.
Poirieria is a genus of large predatory sea snails, marine gastropod molluscs in the subfamily Pagodulinae of the family Muricidae, the rock snails.
Solmissus, or dinner plate jellyfish, is a genus of hydrozoans. Its species are unique among cnidarians in that they actively hunt for prey as opposed to passively waiting for plankton to pass by. They are found in the deep waters of Monterey Bay, California. They are most likely to be found in the deep sea, mid water. They grow to be 20 cm (7.9 in) in diameter. These hydrozoans feed on gelatinous zooplankton, including salps and doliolids, ctenophores, jellyfish, and copepods. However, Solmissus may be limited to feeding on soft-bodied prey by the type of nematocysts on their tentacles (Mills).
Coelenterazine is a luciferin, a molecule that emits light after reaction with oxygen, found in many aquatic organisms across eight phyla. It is the substrate of many luciferases such as Renilla reniformis luciferase (Rluc), Gaussia luciferase (Gluc), and photoproteins, including aequorin, and obelin. All these proteins catalyze the oxidation of this substance, a reaction catalogued EC 1.13.12.5.
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.
Aulactinia is a genus of sea anemones in the family Actiniidae.
Briareidae is a family of corals, a member of the phylum Cnidaria.
Anemonia is a genus of sea anemones belonging to the family Actiniidae.
Renilla koellikeri is a species of sea pen that has been reported from the southern coast of California, including Santa Barbara, California.
Renilla muelleri is a species of sea pansy. It has been reported from the Gulf Coast of the United States, notably the Florida panhandle, but is also reported from the eastern coast of South America. It is thought to be a euryhaline littoral species, found to a depth of up to 150 meters.
Ramirezia is a genus of sea anemones of the family Acontiophoridae. It currently includes only one species.
Hauchiella is a genus of annelids belonging to the family Terebellidae.
Irenium is a genus of hydrozoans in the family Eirenidae.
