Notonykia Africanae
''Notonykia africanae'' ('African clubhook-squid',) is a species of squid in the family Onychoteuthidae. It is the type species of the genus '' Notonykia''. While the mature size of the species is unknown, it is known to reach a mantle length of at least 180 mm. Tentacles reach approximately 70% of the mantle length, and contain 14-20 club hooks. Arms are known to reach 27-45% (arm I) and 33-55% (arms II-IV) of the mantle length; each containing 50-60 suckers. The species is located in southern waters off Australia, Tasmania, New Zealand and South Africa South Africa, officially the Republic of South Africa (RSA), is the Southern Africa, southernmost country in Africa. It is bounded to the south by of coastline that stretch along the Atlantic Ocean, South Atlantic and Indian Oceans; to the ....

Notonykia Nesisi
''Notonykia nesisi'' is a species of squid in the family Onychoteuthidae. It is differentiated from ''Notonykia africanae'' by the shape of the tentacles. While the species is only known from immature specimens, it is known to achieve a mantle A mantle is a piece of clothing, a type of cloak. Several other meanings are derived from that. Mantle may refer to: *Mantle (clothing), a cloak-like garment worn mainly by women as fashionable outerwear **Mantle (vesture), an Eastern Orthodox ve ... length of at least 100 mm. The tentacles are about 65-115% of the mantle length, and contain 6-18 hooks.

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.

Kir 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] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
