Walvisteuthis
''Walvisteuthis'', the stubby hook squids, is a genus of squid in the family Onychoteuthidae. The genus contains four species. They are characterised by possessing oval fins which are not drawn-out posteriorly, the Gladius (cephalopod), gladius has elongated-rhomboid vanes and a short, blunt rostrum which is perpendicular to tip of gladius, the gladius is visible beneath skin at the dorsal midline and they only have primary Nuchal crest (cephalopod), occipital folds.

''Walvisteuthis rancureli'' is a species of squid from the family Onychoteuthidae. The species can be found in the Eastern Central Atlantic and Eastern Indian oceans, and members of the species are gonochoric In biology, gonochorism is a sexual system where there are two sexes and each individual organism is either male or female. The term gonochorism is usually applied in animal species, the vast majority of which are gonochoric. Gonochorism contrast .... References Hooked squid Cephalopods described in 1981 {{Squid-stub ...

Kir Nazimovich Nesis
Kir Nazimovich Nesis (9 January 1934 – 8 January 2003) was a Russian marine biologist and malacologist, specialising in cephalopods. Early life and education Nesis was born in Moscow on 9 January 1934 to an intellectual family, his father was an architect and his mother was an economic geographer. His father was arrested by the Soviet state in 1938 and executed. This would cause some difficulty for Nesis as he was the son of a person who had been executed as an enemy of the state. He initially wanted to study astronomy and he won an All-Union Competition in astronomy for schoolchildren but this career was not open to the son of an "enemy of the nation". He decided instead to become a marine biologist and in 1951 he enrolled in a course at the Moscow Technical Institute for Fisheries and Fishery Management in the Department of Hydrobiology, as this was not among the top ranked Soviet institutions his father's status did not bar him from entry. Career After graduation Nesis was sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gladius (cephalopod)
The gladius (: ''gladii''), or pen, is a hard internal bodypart found in many cephalopods of the superorder Decapodiformes (particularly squids) and in a single extant taxon, extant member of the Octopodiformes, the vampire squid (''Vampyroteuthis infernalis''). It is so named for its superficial resemblance to the Roman Empire, Roman Gladius, short sword of the same name, and is a Vestigiality, vestige of the ancestral mollusc shell, which was external. The gladius is located Dorsal (anatomy), dorsally within the mantle (mollusc), mantle and usually extends for its entire length. Composed primarily of chitin, it lies within the shell sac, which is responsible for its secretion. Some species, like the bigfin reef squid, still has a gladius with some degree of mineralization. Gladii are known from a number of extinct cephalopod groups, including Teudopseina, teudopseids (''e.g.'' ''Actinosepia'', ''Glyphiteuthis'', ''Muensterella'', ''Palaeololigo'', ''Teudopsinia'', ''Teudopsis'', ...

Nuchal Crest (cephalopod)
The nuchal crest in cephalopods is a prominent transverse ridge that extends across the dorsal surface of the head and on to the lateral surfaces at its posterior end. It is often joined at the posterior end to fixed folds of the head integument In biology, an integument is the tissue surrounding an organism's body or an organ within, such as skin, a husk, Exoskeleton, shell, germ or Peel (fruit), rind. Etymology The term is derived from ''integumentum'', which is Latin for "a coverin ... which are perpendicular to the nuchal crest; these are known as nuchal folds. It is also known as the occipital crest and the folds as occipital folds. References Cephalopod zootomy {{Cephalopod-stub ...

Tree Of Life Web Project
The Tree of Life Web Project (ToL) 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amanda Sosnowski
Amanda is a Latin feminine gerundive (i.e. verbal adjective) name meaning, literally, "she who must (or is fit to) be loved". Other translations, with similar meaning, could be "deserving to be loved," "worthy of love," or "loved very much by everyone." Its diminutive form includes Mandy, Manda and Amy. It is common in countries where Germanic and Romance languages are spoken. "Amanda" comes from ''ama-'' (the stem of the Latin verb ''amare'', "to love") plus the feminine nominative singular gerundive ending (''-nda''). Other names, especially female names, were derived from this verb form, such as "Miranda". The name "Amanda" occasionally appears in Late Antiquity, such as the Amanda who was the "wife of the ex-advocate and ex-provincial governor Aper (q.v.); she cared for his estates and raised their children after he adopted the monastic life: 'curat illa saeculi curas, ne tu cures (Paul. Nol. Epist. 44.4). Accessed 19 April 2021. In England the name "Amanda" first appea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
