Bioluminescent Cnidarians
Bioluminescence is the emission of light during a chemiluminescence reaction by living organisms. Bioluminescence occurs in multifarious organisms ranging from marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, dinoflagellates and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus ''Vibrio''; in others, it is autogenic, produced by the animals themselves. In most cases, the principal chemical reaction in bioluminescence involves the reaction of a substrate called luciferin and an enzyme, called luciferase. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin or cypridina luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin resulting in excited state oxyluciferin, which is the light emitter of the reac ...

Octocorallia Genera
Octocorallia, along with Hexacorallia, is one of the two extant classes of Anthozoa. It comprises over 3,000 species of marine and brackish animals consisting of colonial polyps with 8-fold symmetry, commonly referred informally as "soft corals". It was previously known by the now unaccepted scientific names Alcyonacea and Gorgonacea, both deprecated , and by the also deprecated name of Alcyonaria, in earlier times. Its only two orders are Malacalcyonacea and Scleralcyonacea, which include corals such as those under the common names of blue corals, sea pens, and gorgonians (sea fans and sea whips). These animals have an internal skeleton secreted by their mesoglea, and polyps with tipically eight tentacles and eight mesenteries. As is the case with all cnidarians, their complex life cycle includes a motile, planktonic phase (a larva called planula), and a later characteristic sessile phase. Octocorals have existed at least since the Ordovician period, as shown b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cnidaria
Cnidaria ( ) is a phylum under kingdom Animalia containing over 11,000 species of aquatic invertebrates found both in fresh water, freshwater and marine environments (predominantly the latter), including jellyfish, hydroid (zoology), hydroids, sea anemones, corals and some of the smallest marine parasites. Their distinguishing features are an uncentralized nervous system distributed throughout a gelatinous body and the presence of cnidocytes or cnidoblasts, specialized cells with ejectable flagella used mainly for envenomation and capturing prey. Their bodies consist of mesoglea, a non-living, jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell (biology), cell thick. Cnidarians are also some of the few animals that can reproduce both sexually and asexually. Cnidarians mostly have two basic body forms: swimming medusa (biology), medusae and sessility (motility), sessile polyp (zoology), polyps, both of which are radially symmetrical with mou ...

Willy Kükenthal
Wilhelm (Willy) Georg Kükenthal (4 August 1861, Weißenfels – 20 August 1922, Berlin) was a German zoologist. He was the older brother of botanist and theologian Georg Kükenthal (1864–1955). Kükenthal specialized in the Octocorallia and on marine mammals. He edited, along with Thilo Krumbach, a landmark series of eight volumes in the ''Handbuch der Zoologie'' series which extensively reviewed and compiled the state of zoological knowledge of the time. Life Kükenthal was born to August Kükenthal (1826-1910) and Minna Wimmer (died 1917) and went to school at Weißenfels and Halle before joining the University of Munich where he studied mineralogy and later zoology at Jena, earning his doctorate at the latter institution in 1884 for studying lymphoid cells in annelids. He travelled around the North Sea with B. Weißenborn and joined the zoology department Jena under Ernst Haeckel Ernst Heinrich Philipp August Haeckel (; ; 16 February 1834 – 9 August 1919) was a G ...
