Chtenopteryx Sicula
''Chtenopteryx sicula'', also known as the comb-finned squid or toothed-fin squid, is a species of squid native to at least the Mediterranean Sea. It is characterised by several distinct morphological features: ocular photophores are present but visceral photophores are absent, arm suckers are arranged in at least 4 series distally, and club suckers are borne in more than 8 series. The type specimen was collected off Messina, Italy; the specific name ''sicula'' means "of Sicily". It is deposited at the Muséum d'Histoire Naturelle (Musée Barla) in Nice Nice ( , ; Niçard: , classical norm, or , nonstandard, ; it, Nizza ; lij, Nissa; grc, Νίκαια; la, Nicaea) is the prefecture of the Alpes-Maritimes department in France.

Georg Grimpe
Johann Georg Grimpe (16 February 1889, in Leipzig – 22 January 1936) was a German zoologist and malacologist. He studied zoology and comparative anatomy at the University of Leipzig, where under the influence of Carl Chun (1852–1914), he focused his energies towards research of marine fauna, especially cuttlefish. He conducted studies at marine biology stations in Naples, Villefranche-sur-Mer, Helgoland and Monaco. In 1912 he obtained his doctorate with a dissertation on the vascular system of Octopoda.Grimpe, Johann Georg @ NDB/ADB Deutsche Biographie After graduation, he worked as an assistant at the Leipzig Zoo, being tasked with scientific design issues concerning its [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Appellöf
Jakob Johan Adolf Appellöf ( Garda on Gotland 2 November 1857 – Uppsala 5 January 1921) was a Swedish marine zoologist. Appellöf matriculated at Uppsala University in 1877, earned his PhD in 1886 and became a docent of zoology in 1887. In 1889 he received the position of conservator at the Museum of Bergen in Bergen, Norway. He was appointed professor of comparative anatomy in Uppsala in 1910. With a donation from the sawmill magnate Bünsow, Appellöf established the Klubban Biological Station of Uppsala University, a station for the study of marine biology located on the west coast of Sweden. In 1919 he was elected a member of the Royal Swedish Academy of Sciences and in 1920 of the Royal Society of Sciences in Uppsala. He made several important contributions to the knowledge of cephalopod A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus.

Jean Baptiste Vérany
Chevalier Jean Baptiste Vérany (1800, in Nice – 1865) was a French pharmacist and naturalist who specialised in the study of cephalopods. In 1846, with Jean-Baptiste Barla (1817–1896), he founded the Muséum d'histoire naturelle de Nice. Vérany discovered and described many species. André Étienne d'Audebert de Férussac named ''Chiroteuthis veranyi ''Chiroteuthis veranii'', commonly known as the long-armed squid, is a species of Chiroteuthidae, chiroteuthid squid.

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 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 jet propulsion, and largely locate their prey by sight. They are among the most intelligent o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the Season, solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions of Earth, polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical
The subtropical zones or subtropics are geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical (Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example Southeast China and the Southeastern United States, and dry summer or Mediterranean climate (Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the cooler months, such as the Mediterranean Basin or Southern California. Subtropical climates can also occur at high elevations within the tropics, such as in the southern end of the Mexican Plateau and in Da Lat of the Vietnamese Central Highlands.

Georg Johann Pfeffer
Georg Johann Pfeffer (1854–1931) was a German zoologist, primarily a malacologist, a scientist who studies mollusks. Pfeffer was born in Berlin. In 1887 he became curator of the , which was established in 1843 and destroyed during World War II. Pfeffer's published writings were mainly about cephalopods. The World Register of Marine Species database lists 133 marine taxa named by Pfeffer When Pfeffer's name is listed as an authority for a taxon such as the land snail genus ''Lamellaxis'' Strebel & Pfeffer, 1882, his name is ''not'' simply an orthographic error for the more commonly encountered molluscan authority Pfeiffer, i.e. Ludwig Karl Georg Pfeiffer, who lived 50 years earlier, from 1805 to 1877. Georg Johann Pfeffer also studied amphibians and reptiles, naming several new species. Two species of reptiles are named in his honor, ''Calamaria pfefferi Pfeffer's reed snake, ''Calamaria pfefferi'', is a species of dwarf snake in the family Colubridae. The spe ...
