Lycoteuthinae
Lycoteuthinae is a subfamily of squid from the family Lycoteuthidae. They are found in tropical and subtropical waters. They are characterised by the possession of oval photophores on the tentacles, eyeballs and viscera in all species and on the arms, head, mantle and fins in some. Some species also show strong sexual dimorphism. The subfamily contains all of the species classified under Lycoteuthidae, except for '' Lampadioteuthis megaleia'' which differs from the Lycoteuthins by the bearing of a hectocotylised arm in males. Genera and species The taxa within the subfamily Lycoteuthinae are: *''Lycoteuthis'' Pfeffer, 1900 **''Lycoteuthis lorigera'' ( Steenstrup, 1875) **''Lycoteuthis springeri'' (Voss, 1956) *'' Nematolampas'' Berry, 1913 **'' Nematolampas regalis'' Berry, 1913 **'' Nematolampas venezuelensis'' Arocha, 2003 *''Selenoteuthis ''Selenoteuthis'' is a monotypic genus of squid from the family Family (from la, familia) is a group of people related either by ...

Lycoteuthidae
The Lycoteuthidae are a family of squid comprising four known genera in two subfamilies. They are small muscular squid characterised by a lack of hooks and by photophores present on the viscera, eyeballs and tentacles. They inhabit tropical and subtropical seas where the diel migrants which stay down in the mesopelagic zone during the day and migrate to the surface to feed at night. Some species show strong sexual dimorphism Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction.

Georg Johann Pfeffer
Georg Johann Pfeffer (1854–1931) was a German zoologist, primarily a malacologist, a scientist who studies mollusks. Pfeffer was born in Berlin. In 1887 he became curator of the , which was established in 1843 and destroyed during World War II. Pfeffer's published writings were mainly about cephalopods. The World Register of Marine Species database lists 133 marine taxa named by Pfeffer When Pfeffer's name is listed as an authority for a taxon such as the land snail genus '' Lamellaxis'' Strebel & Pfeffer, 1882, his name is ''not'' simply an orthographic error for the more commonly encountered molluscan authority Pfeiffer, i.e. Ludwig Karl Georg Pfeiffer Ludwig Karl Georg Pfeiffer, also known as Louis Pfeiffer (4 July 1805 – 2 October 1877), was a German physician, botanist and conchologist.

Tree Of Life Web Project
The Tree of Life Web Project is an Internet project providing information about the diversity and phylogeny of life on Earth. This collaborative peer reviewed project began in 1995, and is written by biologists from around the world. The site has not been updated since 2011, however the pages are still accessible. The pages are linked hierarchically, in the form of the branching evolutionary tree of life, organized cladistically. Each page contains information about one particular group of organisms and is organized according to a branched tree-like form, thus showing hypothetical relationships between different groups of organisms. In 2009 the project ran into funding problems from the University of Arizona. Pages and Treehouses submitted took a considerably longer time to be approved as they were being reviewed by a small group of volunteers, and apparently, around 2011, all activities ended. History The idea of this project started in the late 1980s. David Maddison was wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nematolampas Regalis
''Nematolampas regalis'', the regal firefly squid is a small, little-known species of squid from the family Lycoteuthidae which is found in the subtropical South Pacific Ocean. This squid has a mantle length of 30mm. It may be sexually dimorphic, with the males possibly having very thin elongated arms III, which are increasingly thread like towards their tips, where they do not have any suckers. Arms II are "normal" and have suckers along their length. The third arms have a series of photophores along their length, and there is a small photophore located on each of the tips of arms I and II. The tentacles have two embedded photophores and the largest of the eye's photophores is in the centre. There is a pair of large photophores close to the tip of the mantle on the ventral side mantle, with no other photophores on the body except for a visceral photophore which is also near the tip. There is practically no tail. ''N. regalis'' is known only from the Kermadec Islands The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nematolampas
''Nematolampas'' is a genus of squid from the family Lycoteuthidae. The genus comprises two species both of which are known from only a few males. The type species, ''Nematolampas regalis'' has been recorded from the subtropical South Pacific and the second species, '' Nematolampas venezuelensis'', is from the tropical western North Atlantic. The main distinguishing feature of this genus is that arms III are very elongated and thread-like and have no suckers near their tips. As only males have been captured it is not known if this feature is present in females. Species There are currently two species classified under this genus: *''Nematolampas regalis ''Nematolampas regalis'', the regal firefly squid is a small, little-known species of squid from the family Lycoteuthidae which is found in the subtropical South Pacific Ocean.

Lycoteuthis Springeri
''Lycoteuthis springeri'' is a small species of rarely captured squid from the family Lycoteuthidae. It has three photophores on the posterior portion of the abdomen and the males have a long tail which bears seven deeply embedded long and thin photophores. The males also have photophores on arms II and III, as well as on the head and the mantle. The tentacular clubs and the structure of the suckers on the club and arm are not distinctive. Two of the known specimens were males which had mantle lengths of 80mm and 97mm. The type locality was in the Gulf of Mexico and the holotype A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described.

Japetus Steenstrup
Johannes Japetus Smith Steenstrup FRS(For) HFRSE (8 March 1813 – 20 June 1897) was a Danish zoologist, biologist, and professor. Life Born in Vang, Thy on 8 March 1813, he held a lectorate in mineralogy in Sorø until 1845 when he became a professor of zoology at the University of Copenhagen. He worked on a great many subjects, including cephalopods, and also in genetics, where he discovered the principle of the alternation of generations in some parasitic worms in 1842. Steenstrup discovered (1842) the possibility of using the subfossils of the Postglacial as a means of interpreting climate changes and correlated vegetation change, which he called succession in the recent past. Two of Steenstrup's students, Christian Vaupell and Eugen Warming further developed this line of research. Japetus Steenstrup was a professor to zoologist Johan Erik Vesti Boas, who was also a student of zoologist Carl Gegenbaur, and Hans Christian Gram, inventor of the Gram stain. "Biogra ...

Lycoteuthis
''Lycoteuthis'' is a genus containing two species of squid: '' Lycoteuthis springeri'' and ''Lycoteuthis lorigera''. They are small animals which grow up to 8 cm in length. These squid live in the deep sea at depths of up to 3000 metres, making horizontal migrations within their range along the steep shelves. ''Lycoteuthis'' are particularly characterised by their photophores, shining organs which give them their German name "Miracle Lamps". The photophores are located in various parts of the body, with males having them on their mantle and head. The light of these photophores results from bioluminescence. The photophores serve as camouflage Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the ..., since the body appears almost transparent by the light effects and normally visible ...
