Pinnoctopus Cordiformis
''Pinnoctopus cordiformis'' is a species of octopus found around the coasts of New Zealand. Description ''Pinnoctopus cordiformis'' is identifiable by its orange-brown or purple-grey colouration; iridescent white spots are found on the arms and web. No white spots can be seen on the mantle.Anderson TJ 1994. Taxonomy and ecology of shallow benthic octopuses in north-eastern New Zealand. MSc thesis. Auckland, New Zealand, University of Auckland. ''Pinnoctopus'' has been seen to reach sizes of over 1m in length and 9 kilograms in weight, however, specimens of this size are seldom seen, due to residing in deeper waters. ''Pinnoctopus cordiformiss closest relative is ''Octopus huttoni''. The two can be easily distinguished by comparing a range of features: ''Octopus huttoni'' is about the size of a fist when fully mature, so is considerably smaller than the ''P, cordiformis''; ''Octopus huttoni'' has a single row of suckers, which run up each tentacle, as opposed to ''Pinnoctopus ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Buller's Albatross
Buller's albatross (''Thalassarche bulleri'') or Buller's mollymawk, is a small mollymawk in the albatross family. It breeds on islands around New Zealand, and feeds in the seas off Australia and the South Pacific. Taxonomy Mollymawks are a type of albatross that belong to the family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages called naricorns that attach to the upper bill, although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into seven to nine horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy rich food source for chicks and for the adults during their long flights. They also have a salt gland that is situated above the nasal pa ...

Cephalopods Described In 1832
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 identified. Tw ...

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. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Enteroctopus
''Enteroctopus'' is an octopus genus whose members are sometimes known as giant octopus. Etymology The generic name ''Enteroctopus'' was created by Alphonse Tremeau de Rochebrune and Jules François Mabille in 1887 and published in 1889, joining Ancient Greek 'gut' and , thus 'octopus ith arms similar toguts.' Description ''Enteroctopus'' is a genus of generally temperate octopuses. Members of this genus are characterized by their large size and are often known as giant octopuses. ''Enteroctopus'' species have distinct longitudinal wrinkles or folds dorsally and laterally on their bodies. Their heads are distinctly narrower than the mantle width. The hectocotylus of the males in this genus, found on the third right arm, is long and narrow in comparison with other genera in the family Octopodidae, often comprising one-fifth the length of the arm. Octopuses in this genus have large, paddle-like papillae instead of the more conical papillae in other octopus genera. Spe ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Octopus Maorum
''Macroctopus maorum'' is known more commonly as the Maori octopus or the New Zealand octopus (''wheke'' in Maori). They can also be known as ''Pinnoctopus cordiformis'', is found in the waters around New Zealand New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island count ... and southern Australia. ''M. maorum'' is one of the largest and most aggressive octopus species living in the New Zealand and Australian waters. They feed mainly on crustaceans and fish. Although they have a short life span, the females lay thousands of eggs and are very protective of them. Identification ''Macroctopus maorum'' is a large octopus and it is regularly described as a ‘robust’ species, it is a member of the ''Octopus macropus'' species complex. The morphological traits characteristic of this complex are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Cook Strait
Cook Strait ( mi, Te Moana-o-Raukawa) separates the North and South Islands of New Zealand. The strait connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast. It is wide at its narrowest point,McLintock, A H, Ed. (1966''Cook Strait''from An Encyclopaedia of New Zealand, updated 18-Sep-2007. Note: This is the distance between the North Island and Arapaoa Island; some sources give a slightly larger reading of around , that between the North Island and the South Island. and is considered one of the most dangerous and unpredictable waters in the world. Regular ferry services run across the strait between Picton in the Marlborough Sounds and Wellington. The strait is named after James Cook, the first European commander to sail through it, in 1770. In Māori it is named ''Te Moana-o-Raukawa'', which means ''The Sea of Raukawa''. Raukawa is a type of woody shrub native to New Zealand. History Approximately 18,000 years ago during the Last Gla ...

Kupe
Kupe ( ~1180-1320) was a legendary Polynesian explorer, navigator and great rangatira of Hawaiki, who is said to have been the first human to discover New Zealand. Whether Kupe existed historically is likely but difficult to confirm. He is generally held to have been born to a father from Rarotonga and a mother from Raiatea, and probably spoke a proto-Māori language similar to Cook Islands Māori or Tahitian. His voyage to New Zealand would ensure that the land would be known to the Polynesians, and he would therefore be responsible for the genesis of Māori civilisation. Kupe features prominently in the mythology and oral history of some Māori iwi (tribes), but the details of his life differ between iwi. Various legends and histories describe Kupe's extensive involvement in the settlement of Aotearoa, around 1000–1300 CE, with many talking of his achievements, such as the hunting and destruction of the great octopus, Te Wheke-a-Muturangi.

Polynesian Navigator
Polynesian navigation or Polynesian wayfinding was used for thousands of years to enable long voyages across thousands of kilometers of the Pelagic zone, open Pacific Ocean. Polynesians made contact with nearly every island within the vast Polynesian Triangle, using outrigger canoes or double-hulled canoes. The double-hulled canoes were two large hulls, equal in length, and lashed side by side. The space between the paralleled canoes allowed for storage of food, hunting materials, and nets when embarking on long voyages. Polynesian navigators used wayfinding techniques such as the navigation by the stars, and observations of birds, ocean swells, and wind patterns, and relied on a large body of knowledge from oral tradition. Navigators travelled to small inhabited islands using wayfinding techniques and knowledge passed by oral tradition from master to apprentice, often in the form of song. Generally, each island maintained a guild of navigators who had very high status; in times ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
