Lepidoteuthis
''Lepidoteuthis grimaldii'', also known as the Grimaldi scaled squid, is a large squid growing to in mantle length. It is named after the Grimaldi family, reigning house of Monaco. Prince Albert I of Monaco was an amateur teuthologist who pioneered the study of deep sea squids by collecting the 'precious regurgitations' of sperm whales. The Grimaldi scaled squid was first collected from the stomach contents of a sperm whale.Albert 1er of Monaco. "Notes sur un Cachalot." ''Bulletin du Muséum d’histoire naturelle'' 1895, no. 8. It is a widely distributed species in tropical and subtropical areas of the North and South Atlantic, the southern Indian Ocean and the Pacific Ocean, where it has been recorded off Japan and in the west Pacific.

Cephalopod Dermal Structures
Cephalopods exhibit various dermal structures on their mantle (mollusc), mantles and other parts. These may take the form of conspicuous warts, cushions, papillae or scales, though in many species they are microscopic tubercles.Young, R.E., M. Vecchione & K.M. Mangold (2001)Cephalopod Mantle Armature Tree of Life Web Project. The most elaborate forms are found among the oceanic squid of the order Teuthida, with some of these species Common name, being dubbed the scaled squid.Roper, C.F.E. & C.C. Lu (1990). ''Smithsonian Contributions to Zoology'', Number 493: 1–40. Morphology and composition Most cephalopod dermal structures take the form of tubercles, and these are the only cartilage, cartilaginous dermal structures (the various "dermal cushions" being composed of other forms of connective tissue). All three main types of cartilage found in vertebrates are represented among the different squid species: hyaline cartilage, hyaline, elastic cartilage, elastic and fibrocartilage. Tu ...

Cephalopod Size
Cephalopods, which include squids and octopuses, vary enormously in size. The smallest are only about long and weigh less than at maturity, while the giant squid can exceed in length and the colossal squid weighs close to half a tonne (), making them the largest living invertebrates. Living species range in mass more than three-billion-fold, or across nine orders of magnitude, from the lightest hatchlings to the heaviest adults. Certain cephalopod species are also noted for having #Anatomical superlatives, individual body parts of exceptional size.#Nilssonetal2012, Nilsson ''et al.'', 2012:683 Cephalopods were at one time the largest organism, largest of all organisms on Earth, and numerous species of comparable size to the largest present day squids are known from the fossil record, including enormous examples of ammonoids, belemnoids, nautiloids, orthoceratoids, teuthids, and vampyromorphids. In terms of mass, the largest of all known cephalopods were likely the giant shelled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octopoteuthoidea
Octopoteuthoidea is a superfamily of squid in the order Oegopsida. It consists of two small families and three genera: * Superfamily Octopoteuthoidea ** Family Octopoteuthidae *** Genus '' Octopoteuthis'' *** Genus '' Taningia'' ** Family Lepidoteuthidae ''Lepidoteuthis grimaldii'', also known as the Grimaldi scaled squid, is a large squid growing to in mantle length. It is named after the Grimaldi family, reigning house of Monaco. Prince Albert I of Monaco was an amateur teuthologist who pi ... *** Genus '' Lepidoteuthis'' Members of ''Octopoteuthoidea'' are deep-sea squids characterized by robust bodies and relatively short arms compared to other squids. Many species exhibit bioluminescence, which they use for camouflage and communication in the deep ocean. Notably, ''Taningia danae'' can reach mantle lengths of up to 2 meters and produces powerful bioluminescent displays using photophores on its arms, potentially to stun prey or signal conspecifics. These squids i ... [...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'', ...

Squid
A squid (: squid) is a mollusc with an elongated soft body, large eyes, eight cephalopod limb, arms, and two tentacles in the orders Myopsida, Oegopsida, and Bathyteuthida (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, Symmetry (biology)#Bilateral symmetry, bilateral symmetry, and a mantle (mollusc), 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 Ecological niche, 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 swal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert I, Prince Of Monaco
Albert I (Albert Honoré Charles Grimaldi; 13 November 1848 – 26 June 1922) was Prince of Monaco from 10 September 1889 until his death in 1922. He devoted much of his life to oceanography, exploration and science. Alongside his expeditions, Albert I's reign oversaw major reforms on political, social, and economic levels, with the Monégasque Revolution leading to the end of absolute monarchy and his promulgation of a constitution in 1911. Early life Born on 13 November 1848 in Paris, France, the son of Prince Charles III (1818–1889), and Countess Antoinette Ghislaine de Merode (1828–1864), a Belgian noblewoman, maternal aunt of Donna Maria Vittoria dal Pozzo, Princess della Cisterna, Duchess consort of Aosta and Queen consort of Spain. As a young man, Prince Albert served in the Spanish Navy as a navigator. During the Franco-Prussian War, he joined the French Navy where he was awarded the Legion of Honor. In addition to his interest in oceanographic studies, Alber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntype
In biological nomenclature, a syntype is any one of two or more biological types that is listed in a description of a taxon where no holotype was designated. Precise definitions of this and related terms for types have been established as part of the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants. In zoology In zoological nomenclature, a syntype is defined as "Each specimen of a type series (q.v.) from which neither a holotype nor a lectotype has been designated rts. 72.1.2, 73.2, 74 The syntypes collectively constitute the name-bearing type." (Glossary of the zoological Code). Historically, it was common to describe a new species or subspecies from several syntypes without designating a holotype, but this practice is generally frowned upon by modern taxonomists, and most are gradually being replaced by lectotypes. Those that still exist are still considered name-bearing types. A lectotype may be designated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sperm Whale
The sperm whale or cachalot (''Physeter macrocephalus'') is the largest of the toothed whales and the largest toothed predator. It is the only living member of the Genus (biology), genus ''Physeter'' and one of three extant species in the sperm whale superfamily Physeteroidea, along with the pygmy sperm whale and dwarf sperm whale of the genus ''Kogia''. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. Females and young males live together in groups, while mature males (bulls) live solitary lives outside of the mating season. The females cooperate to protect and Lactation, nurse their young. Females give birth every four to twenty years, and care for the calves for more than a decade. A mature, healthy sperm whale has no natural predators, although calves and weakened adults are sometimes killed by Cetacea#Social relations, pods of killer whales (orcas). Mature males average in length, with the head represent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teuthologist
Teuthology (from Ancient Greek, Greek τεῦθος, "Common Cuttlefish, cuttlefish, European squid, squid", and -λογία, ''-logy, -logia'') is the study of Cephalopod, cephalopods, which are members of the class Cephalopod, Cephalopoda in the phylum Mollusca. Some common examples of cephalopods are octopus, squid, and cuttlefish. Teuthology is a large area of study that covers cephalopod life cycles, reproduction, evolution, anatomy, and taxonomy. Teuthology is a specific branch of malacology, the study of molluscs. A teuthologist is a scientist who studies teuthology. Research Highlights 2023 The publication of the English translation of Albin O Ebersbach's thesis on the detailed descriptions of cirrate octopods marks an expansion of access to important taxonomical identifying information in teuthology. The third paper in the series led by Tristian Joseph Verhoeff revisiting cirrate octopods is published. 2022 Several papers describing new species of cephalopo ...

Chatham Rise
The Chatham Rise is an area of ocean floor to the east of New Zealand, forming part of the Zealandia continent. It stretches for some from near the South Island in the west, to the Chatham Islands in the east. It is New Zealand's most productive and important fishing ground, as well as important habitat for whales. Relative to the rest of the Pacific Ocean waters around New Zealand, the Chatham Rise is relatively shallow, no more than deep at any point. This shallowness is made more remarkable by the depth of the ocean immediately to the north and south. To the northeast, the Hikurangi Trough, an extension of the much deeper Kermadec Trench, drops to below close to the New Zealand coast, and further from the coast the Rise borders on the Hikurangi Plateau. To the south, similar depths are achieved in the Bounty Trough. Past the eastern end of the rise, the sea floor drops away to the abyssal plain. Geology Geologically and tectonically, the Chatham Rise can be thought of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand
New Zealand () is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and List of islands of New Zealand, over 600 smaller islands. It is the List of island countries, sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The Geography of New Zealand, country's varied topography and sharp mountain peaks, including the Southern Alps (), owe much to tectonic uplift and volcanic eruptions. Capital of New Zealand, New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and subsequently developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
