Renilla reniformis, the sea pansy, is a species of soft coral in the family Renillidae. [1] It is native to warm continental shelf waters of the Western Hemisphere. [ 2 ] [ 3 ] It is frequently found washed ashore on North East Florida beaches following northeasterly winds or rough surf conditions.
Renilla muelleri (also spelled R. mulleri or R. müilleri) is a species of sea pansy.It has been reported from the Gulf Coast of the United States, notably the Florida panhandle, [2] but is also reported from the eastern coast of South America. [3]

A second category of subregisters comprises regional species databases such as the African Register of Marine Species, Belgian Register of Marine Species, etc., while a third comprises thematic subsets such as the World Register of Deep-Sea species (WoRDSS), World Register of Introduced Marine Species (WRiMS), etc. In all of these cases, the ...
The two main subclasses of Anthozoa are the Hexacorallia, members of which have six-fold symmetry and includes the stony corals, sea anemones, tube anemones and zoanthids; and the Octocorallia, which have eight-fold symmetry and includes the soft corals and gorgonians (sea pens, sea fans and sea whips), and sea pansies.
The sea pens' ability to be clumped together and spatially unpredictable hinders sea stars' predation abilities. [9] When touched, some sea pens emit a bright greenish light; this is known as bioluminescence. They may also force water out of their bodies for defence, rapidly deflating and retreating into their peduncle.
Also well studied is the sea pansy, Renilla reniformis. In this organism, the luciferase (Renilla-luciferin 2-monooxygenase) is closely associated with a luciferin-binding protein as well as a green fluorescent protein . Calcium triggers release of the luciferin (coelenterazine) from the luciferin binding protein.
Renilla-luciferin 2-monooxygenase, Renilla luciferase, or RLuc, is a bioluminescent enzyme found in Renilla reniformis, belonging to a group of coelenterazine luciferases.Of this group of enzymes, the luciferase from Renilla reniformis has been the most extensively studied, and due to its bioluminescence requiring only molecular oxygen, has a wide range of applications, with uses as a reporter ...
