Macrotritopus
''Macrotritopus'' is a poorly known genus of octopuses in the family Octopodidae. As it stands, ''Macrotritopus'' contains one valid described species, ''Macrotritopus defilippi''. Two poorly described, unresolved taxa which are known only from planktonic hatchlings have been tentively assigned ''Macrotritopus equivocus'' and '' M. scorpio'', as well as a further three undescribed Indo-Pacific species. ''Macrotritopus'' was originally described from a single juvenile specimen which was named ''Macrotritopus equivocus'' notable for having an elongated third arm. This specimen gave the name ''Macrotritopus'' larva to this form of paralarva which was misidentified as the newly hatched juveniles of ''Scaeurgus unicirrhus''. When the eggs of ''M. defilippi'', which were kept in captivity, hatched and the resultant larvae were observed to be of the ''Macrotritopus'' larval type then the juveniles were connected with the adults. This means that the type species of ''Macrotritopus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrotritopus Defilippi
''Macrotritopus defilippi'', commonly known as the Lilliput longarm octopus or the Atlantic longarm octopus, is a small species of octopus, a marine cephalopod mollusc of the order Octopoda. This species occurs in the Atlantic Ocean, the Mediterranean Sea and the Indian Ocean. Its typical habitat is shallow sandy areas. Its yellowish-brown colouration enables it to blend into its surroundings making it well-camouflaged when stationary. In the Caribbean it has been found that when it moves around, it does so in such a way as to closely resemble the swimming behaviour of the plate fish (''Bothus lunatus''), a bottom-dwelling flounder which inhabits the same waters. Description ''Macrotritopus defilippi'' is a small octopus with relatively long arms and a mantle length of up to . As is the case in most octopuses, the skin is variable in colour. It is usually either plain or speckled and closely matches the colour of its surroundings, the sandy plains on which it lives. Where the s ...

Cephalopod Genera
A cephalopod is any member of the molluscan class Cephalopoda ( Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles ( muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by '' Nautilus'' and '' Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ...

Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...

Octopuses
An octopus ( : octopuses or octopodes, see below for variants) is a soft-bodied, eight- limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxon Inquirendum
In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation. The use of the term in English-language biological literature dates back to at least the early nineteenth century. The term taxon inquirendum is broader in meaning and refers to an incompletely defined taxon of which the taxonomic validity is uncertain or disputed by different experts or is impossible to identify the taxon. Further characterization is required. See also * Glossary of scientific naming * '' Candidatus'', a proposed taxa based on incomplete evidence * '' incertae sedis'', a taxon of uncertain position in a classification * ''nomen dubium In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application.

Guy Coburn Robson
Guy Coburn Robson (1888–1945) was a British zoologist, specializing in Mollusca, who first named and described '' Mesonychoteuthis hamiltoni'', the colossal squid. Robson studied at the marine biological station in Naples, and joined the staff of the Natural History Museum in 1911, becoming Deputy Keeper of the Zoology Department from 1931 to 1936. Evolution Robson is best known for his major book ''The Variations of Animals in Nature'' (co-authored with O. W. Richards, 1936) which argued that although the fact of evolution is well established, the mechanisms are largely hypothetical and undemonstrated.Allee, W. C. (1937)''The Variation of Animals in Nature: A Critical Summary and Judgment of Evolutionary Theories by G. C. Robson, O. W. Richards'' ''American Journal of Sociology'' 42 (4): 596–597. The book claims that most differences among animal populations and related species are non-adaptive. It was published before major developments in the modern synthesis and contains ...

Chevalier Jean Baptiste Vérany (1800, in Nice – 1865) was a French pharmacist and naturalist who specialised in the study of cephalopods.
