Doryteuthis Surinamensis
''Doryteuthis'' is a genus of squid from the waters of the western Atlantic and eastern Pacific off the coast of the Americas species are the common inshore squids of American waters. Some species are important quarry species for fisheries. In ''Doryteuthis'' the tentacular clubs are expanded and bear suckers in 4 series. The hectocotylus is on the left ventral arm IV with unmodified suckers near the base, lack of a ventral crest while the reduced on elongated stalks form papillae on the dorsal series or on both dorsal and ventral series. The fins are situated in a posterior position. The spermatophore has a short, cement body cement body and they do not have any photophores. Taxonomy ''Doryteuthis'' is divided into two subgenera, ''Amerigo'' and ''Doryteuthis''. The species in each subgenus are: * Subgenus ''Amerigo'' ** ''Doryteuthis gahi'' (d'Orbigny, 1835) Patagonian squid ** ''Doryteuthis ocula'' (Cohen, 1976) bigeye inshore squid ** ''Doryteuthis opalescens'' (Berry, 1911) ...

Adolf Naef
Adolf Naef (1 May 1883 – 11 May 1949) was a Swiss zoologist and palaeontologist who worked on cephalopods and systematics. Although he struggled with academic politics throughout his career and difficult conditions during World War I and II, his work had lasting influences on the fields of phylogenetics, morphology, and embryology. Life Naef was born in Herisau, Switzerland, to parents Martin and Berta. In 1904, he began studying philosophy and literature at the University of Zurich, but soon switched to natural sciences. He graduated in 1908 and went on to pursue a PhD under the guidance of Arnold Lang (1855—1914), a former Professor of Jena University and close friend of Ernst Haeckel as well as a long-time associate of Anton Dohrn.Rieppel, Olivier (2016).

Although initially planning to collect eggs from a variety of animals, he ended up stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doryteuthis Opalescens
''Doryteuthis opalescens'', the opalescent inshore squid or market squid, is a small squid ( mantle length (ML) up to 190 mm) in the family Loliginidae. It is a myopsid squid, which is the near shore group and that means that they have corneas over their eyes. The species lives in the eastern Pacific Ocean from Mexico's Baja California peninsula to Alaska, United States, and as an inshore squid it can be found with a range of off the coast. Description Adult ''Doryteuthis opalescens'' can reach a total size of 11 inches. Males are typically larger with a mantle length of 5 – 3 1/2 inches , while females are 5 –7 inches in mantle length.Morris, Robert H., Donald P. Abbott, Eugene R. Haderlie. 1980. ''Intertidal Invertebrates of California''. Stanford: Stanford University Press. The mantle of ''D. opalescens'' is not fused to the head and its body is 4 to 5 times longer than it is wide, with fins equal in both length and width. This squid has 8 arms with 2 longer te ...

Cephalopod Genera
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ide ...

Doryteuthis Plei
''Doryteuthis plei'', also known as the slender inshore squid or arrow squid, is a medium-sized squid belonging to the family Loliginidae. It occurs abundantly in coastal waters of the Atlantic Ocean, from Argentina northward to North Carolina. Description As both common names imply, these squid have elongate, cylindrical bodies with a length to width ratio of 7:1. The arms are in contrast short and weak; the two tentacles are somewhat less than the mantle length. The rhombus-shaped fins are large, up to about 50 percent of the mantle length. Running the ventral length of the mantle is a noticeable ridge. The squid are a reddish orange colour with a large complement of chromatophores. The suckers of the arms possess blunt teeth. On the meaty ends (''clubs'') of the tentacles, there are four rows of suckers; the inner two (''mesial'') rows are three times as large as the outer two (''marginal'') rows. The larger suckers have horny rings with up to 45 teeth. These squid reach a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Alexandre Lesueur
Charles Alexandre Lesueur (1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French Natural history, naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle (''Apalone spinifera''), smooth softshell turtle (''Apalone mutica, A. mutica''), and common map turtle (''Graptemys geographica''). Both Mount Lesueur and Lesueur National Park in Western Australia are named in his honor. Early life Charles Alexandre Lesueur was born on January 1, 1778, to Jean-Baptiste Denis Lesueur and Charlotte Thieullent. Charlotte died when Charles was sixteen years old, and Charles' maternal grandmother took care of him and his siblings. Charles attended the Collège du Havre and possibly the Ecole publique des mathématiques et d'hydrographie. He was in military service in a cadet bat ...

Doryteuthis Pealeii
The longfin inshore squid (''Doryteuthis pealeii'') is a species of squid of the family Loliginidae. Description This species of squid is often seen with a reddish hue, but like many types of squid can manipulate its color, varying from a deep red to a soft pink. The dorsal mantle length of some males can reach up to 50 cm, although most squid commercially harvested are smaller than 30 cm long. This species exhibits sexual dimorphism, with most males growing faster and reaching larger sizes than females. Distribution The longfin inshore squid is found in the North Atlantic, schooling in continental shelf and slope waters from Newfoundland to the Gulf of Venezuela. It is commercially exploited, especially in the range from the Southern Georges Bank to Cape Hatteras. The population makes seasonal migrations that appear to be related to bottom water temperatures; they move offshore during late autumn to overwinter along the edge of the continental shelf and return insh ...

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] |
