Luciferidae
Luciferidae is a family of prawns. These prawns are small, characterised by bioluminescence and the loss or reduction of some appendages. They are predators of tiny planktonic crustaceans for which their third pereiopod is adapted to capture by having thick, curved spines covering the limb. Until recently, the family was thought to be monotypic, but a 2016 cladistic analysis recognized a second genus apart from ''Lucifer'', named ''Belzebub Beelzebub ( ; he, ''Baʿal-zəḇūḇ'') or Beelzebul is a name derived from a Philistine god, formerly worshipped in Ekron, and later adopted by some Abrahamic religions as a major demon. The name ''Beelzebub'' is associated with the Ca ...''. References {{Taxonbar, from=Q4189134 Dendrobranchiata Taxa named by Wilhem de Haan Decapod families ...

Dendrobranchiata
Dendrobranchiata is a suborder of Decapoda, decapods, commonly known as prawns. There are 540 extant species in seven families, and a fossil record extending back to the Devonian. They differ from related animals, such as Caridea and Stenopodidea, by the branching form of the gills and by the fact that they do not brood their eggs, but release them directly into the water. They may reach a length of over and a mass of , and are widely shrimp fishery, fished and shrimp farm, farmed for human consumption. Shrimp and prawns While Dendrobranchiata and Caridea belong to different Order (biology), suborders of Decapoda, they are very similar in appearance, and in many contexts such as commercial farming and Fishery, fisheries, they are both often referred to as "shrimp" and "prawn" interchangeably. In the United Kingdom, the word "prawn" is more common on menus than "shrimp", while the opposite is the case in North America. The term "prawn" is also loosely used to describe any large s ...

Lucifer (crustacean)
''Lucifer'' is a little-known and degenerate genus of prawns, the type genus of the family Luciferidae. ''Lucifer'' has a long body, but many fewer appendages than other prawns, with only three pairs of pereiopods remaining, all without claws. It also bears no gills. The females, uniquely among prawns, carry the fertilised eggs on her pleopods until they are ready to hatch. This parallels the development of a similar system in pleocyemates, although the attachment is less strong in ''Lucifer''. The length of the eye-stalks and the form of the petasma are used in distinguishing the eight species from each other. The name ''Lucifer'' is Latin for "light bearer" was given to the genus because of these prawns' bioluminescence. Two species are recognised: *'' Lucifer orientalis'' Hansen, 1919 *''Lucifer typus'' H. Milne-Edwards, 1837 Five nominal ''Lucifer'' species (''L. chacei'', ''L. faxoni'', ''L. hanseni'', ''L. intermedius'', and ''L. penicillifer'') have been reclassifie ...

Belzebub (crustacean)
''Belzebub'' is a genus of prawns in the family Luciferidae. The species which make up the genus ''Belzebub'' were formerly placed in the genus ''Lucifer'' but were separated to form ''Belzebub'' after a cladistic analysis. They are very small planktonic and benthic prawns with an extreme lateral compression of the carapace with elongated mandibles and anteriors of the pereiopods but lacking pereiopods 4 and 5 and any gills. The pereiopods either lack chelae or they are substantially reduced. The sixth abdominal segment of males has two ventral processes and the telson has a strong ventral process. Distinction from ''Lucifer'' ''Belzebub'' is distinguished from the related ''Lucifer'' by have medium length eyestalks and by both sexes having similar eyes, in the species in ''Lucifer'' there is sexual dimorphism in the size of the eyes. In addition, the ventral process of the two on the male's sixth segment is straight and tapering rather than curved and obtuse. Etymology The gene ...

Wilhem De Haan
Wilhem de Haan (7 February 1801 in Amsterdam – 15 April 1855 in Leiden) was a Dutch zoologist. He specialised in the study of insects and crustaceans, and was the first keeper of invertebrates at the Rijksmuseum in Leiden, now Naturalis. He was forced to retire in 1846, when he was partially paralysed by a spinal disease. He was responsible for the invertebrate volume of Siebold's '' Fauna Japonica'', which was published in 1833, and introduced the western world for the first time to Japanese wildlife The wildlife of Japan includes its flora, fauna, and natural habitats. The islands of Japan stretch a long distance from north to south and cover a wide range of climatic zones. This results in a high diversity of wildlife despite Japan's isolati .... He named a great many new taxa, and several taxa are named in his honour. He published significant work on both mantids and phasmids (1842). References *de Haan, W.

Bioluminescence
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, 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 a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin. In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and somet ...

Decapod Anatomy
The decapod (crustaceans such as a crab, lobster, shrimp or prawn) is made up of 20 body segments grouped into two main body parts: the cephalothorax and the pleon (abdomen). Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail: Cephalothorax Head # antennules # antennae #mandibles # first maxillae # second maxillae The head also bears the (usually stalked) compound eyes. The distal portion of a mandible or maxilla which has a sensory function is known as a palp. Thorax / pereon #first maxillipeds #second maxillipeds #third maxillipeds #first pereiopods #second pereiopods #third pereiopods #fourth pereiopods #fifth pereiopods Maxillipeds are appendages modified to function as mouthparts. Particularly in the less advanced decapods, these can be very similar to the pereiopods. Pereiopods are primarily walking legs and are also used for gathering food. They are also the ten legs from which decapods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raffles Bulletin Of Zoology
''The Raffles Bulletin of Zoology'' is a peer-reviewed open-access scientific journal published by the Lee Kong Chian Natural History Museum at the National University of Singapore. It covers the taxonomy, ecology, and conservation of Southeast Asian fauna.Supplements are published as and when funding permits and may cover topics that extend beyond the normal scope of the journal depending on the targets of the funding agency. It was established as the ''Bulletin of the Raffles Museum'' in 1928 and renamed ''Bulletin of the National Museum of Singapore'' in 1961, before obtaining its current title in 1971.

Taxa Named By Wilhem De Haan
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
