They are characterised by possessing oval fins which are not drawn-out posteriorly, the gladius ''Gladius'' () is a Latin word meaning "sword" (of any type), but in its narrow sense it refers to the sword of ancient Roman foot soldiers.

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 se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onychoteuthidae
The hooked squid, family Onychoteuthidae, currently comprise about 20–25 species (several known from only single life stages and thus unconfirmed), in six or seven genera. They range in mature mantle length from 7 cm to a suggested length of 2 m for the largest member, ''Onykia robusta''. The family is characterised by the presence of hooks only on the tentacular clubs, a simple, straight, funnel–mantle locking apparatus, and a 'step' inside the jaw angle of the lower beak. With the exception of the Arctic Ocean, the family is found worldwide.

Gladius (cephalopod)
The gladius (plural: ''gladii''), or pen, is a hard internal bodypart found in many cephalopods of the superorder Decapodiformes (particularly squids) and in a single extant member of the Octopodiformes, the vampire squid (''Vampyroteuthis infernalis''). It is so named for its superficial resemblance to the Roman short sword of the same name, and is a vestige of the ancestral mollusc shell, which was external. The gladius is located dorsally within the mantle and usually extends for its entire length. Composed primarily of chitin, it lies within the shell sac, which is responsible for its secretion. Gladii are known from a number of extinct cephalopod groups, including teudopseids (''e.g.'' '' Actinosepia'', '' Glyphiteuthis'', '' Muensterella'', '' Palaeololigo'', '' Teudopsinia'', ''Teudopsis'', and ''Trachyteuthis''), loligosepiids (''e.g.'' '' Geopeltis'', '' Jeletzkyteuthis'', and '' Loligosepia''), and prototeuthids (''e.g.'' ''Dorateuthis'', '' Paraplesioteuthis'', ...

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, shell, germ or rind. Etymology The term is derived from ''integumentum'', which is Latin for "a covering". In a transferred, or ... 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 anatomy Cephalopod zootomy ...

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] |

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”' aul. Nol. Epist. 44.4 In England the name "Amanda" first appears in 1212 on a b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
