Lolliguncula Panamensis
''Lolliguncula'' is a genus of squid from the family Loliginidae from the eastern Pacific and western Atlantic, known as brief squid. The genus is divided into two subgenera ''Lolliguncula'' and ''Loliolopsis''. They are rather small squids with a maximum mantle length of 120mm, that inhabit shallow warm seas, although some species have been recorded in areas of low salinity. They are typified by having a short mantle, which is round at the posterior; and fins that are broader than long, but which have no posterior lobes. The males produce spermatophores with a long cement body and they lack a ventral crest on their hectocotylus. Their suckers have square teeth which ring the entire margin or are placed distally. The males do not have enlarged suckers on the left ventral arm. The tentacular club is expanded and contains suckers in four series. The two subgenera differ in the morphology of the hectocotylus.

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 ...

Distal
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Lolliguncula Brevis
''Lolliguncula brevis'', or the Atlantic brief squid, is a small species of squid in the Loliginidae family. It is found in shallow parts of the western Atlantic Ocean. Distribution The Atlantic brief squid occurs most frequently in shallow waters along the eastern seaboard of the United States as far north as Delaware. It has also been found in Argentina, Brazil, the British Virgin Islands, Colombia, Mexico, Panama, Puerto Rico, Suriname, Trinidad and Tobago and Venezuela. Description image:Lolliguncula brevis1.jpg, left, ''Lolliguncula brevis'' The female Atlantic brief squid is about 11 cm long and the male 9 cm. The basic colour is dark reddish-brown to yellow-brown and there are many chromatophores on the upper surface which enable the squid to change colour. The Mantle (mollusc), mantle is widest in the middle and tapers to a rounded point at the back. The fins are wider than they are long, rounded and about half the length of the mantle. The mantle has thick musc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tentacular Club
All cephalopods possess flexible limbs extending from their heads and surrounding their beaks. These appendages, which function as muscular hydrostats, have been variously termed arms, legs or tentacles. Description In the scientific literature, a cephalopod ''arm'' is often treated as distinct from a ''tentacle'', though the terms are sometimes used interchangeably, often with the latter acting as an umbrella term for cephalopod limbs. Generally, arms have suckers along most of their length, as opposed to tentacles, which have suckers only near their ends.Young, R.E., M. Vecchione & K.M. Mangold 1999Cephalopoda Glossary Tree of Life web project. Barring a few exceptions, octopuses have eight arms and no tentacles, while squid and cuttlefish have eight arms (or two "legs" and six "arms") and two tentacles.Norman, M. 2000.

Hectocotylus
A hectocotylus (plural: ''hectocotyli'') is one of the arms of male cephalopods that is specialized to store and transfer spermatophores to the female. Structurally, hectocotyli are muscular hydrostats. Depending on the species, the male may use it merely as a conduit to the female, analogously to a penis in other animals, or he may wrench it off and present it to the female. The hectocotyl arm was first described in Aristotle's biological works. Although Aristotle knew of its use in mating, he was doubtful that a tentacle could deliver sperm. The name ''hectocotylus'' was devised by Georges Cuvier, who first found one embedded in the mantle of a female argonaut. Supposing it to be a parasitic worm, in 1829 Cuvier gave it a generic name, combining the Greek word for "hundred" and Latin word for "hollow thing".

Henri Marie Ducrotay De Blainville
Henri Marie Ducrotay de Blainville (; 12 September 1777 – 1 May 1850) was a French zoologist and anatomist. Life Blainville was born at Arques, near Dieppe. As a young man he went to Paris to study art, but ultimately devoted himself to natural history. He attracted the attention of Georges Cuvier, for whom he occasionally substituted as lecturer at the Collège de France and at the Athenaeum Club, London. In 1812 he was aided by Cuvier in acquiring the position of assistant professor of anatomy and zoology in the Faculty of Sciences at Paris. Eventually, relations between the two men soured, a situation that ended in open enmity. In 1819, Blainville was elected a member of the American Philosophical Society in Philadelphia. In 1825 he was admitted a member of the French Academy of Sciences; and in 1830 he was appointed to succeed Jean-Baptiste Lamarck in the chair of natural history at the museum. Two years later, on the death of Cuvier, he obtained the chair of comparative a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
