Hāpuku
The hāpuku, hapuka or whapuku (''Polyprion oxygeneios''), also known as groper, is a wreckfish of the family Polyprionidae, found around southern Australia, southern South America, South Africa, Tristan da Cunha and New Zealand at depths between 30 and 800 m. Its length is between 60 and 180 cm, and it can weigh up to 100 kg. It is sometimes described locally as cod, although that properly refers to other fish. Description Hāpuku are grey in colour with silvery white underbellies, with juveniles generally being blue in colour. They have 10 dorsal spines running along their back, a rounded anal fin and rounded pectoral fins, and a large, powerful, square-shaped tail. Its lower jaw protrudes from the top, and their very large eyes are adapted for hunting and inhabiting low-light conditions.Ocean Hunter Ltd"Hapuku", ''OceanHunter'', n.d.

Kelly Tarlton's Sea Life Aquarium
Kelly Tarlton's Sea Life Aquarium (formerly Kelly Tarlton's Underwater World) is a public aquarium opened in 1985 in Auckland, New Zealand. Located at 23 Tamaki Drive, it was the brainchild of New Zealand marine archaeologist and diver Kelly Tarlton (1937–1985). Built in disused sewage storage tanks, the aquarium used a new form of acrylic shaping, which allowed curved tunnels rather than viewing areas with flat panels only, as in previous aquariums. The project is also one of the first to use moving walkways for people to travel slowly through the viewing areas. History In 1983, Kelly Tarlton proposed building an aquarium in unused sewage tanks underground on the Auckland waterfront. Fish would be viewed through a long acrylic tunnel. The aquarium opened in 1985 after 10 months of construction. Tarlton developed a new method of building an acrylic tunnel by taking large sheets of clear acrylic, cutting them to size and heating them in an oven until they took the shape of th ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Sexual Maturity
Sexual maturity is the capability of an organism to reproduce. In humans it might be considered synonymous with adulthood, but here puberty is the name for the process of biological sexual maturation, while adulthood is based on cultural definitions. Most multicellular organisms are unable to sexually reproduce at birth (animals) or germination (e.g. plants): depending on the species, it may be days, weeks, or years until they have developed enough to be able to do so. Also, certain cues may trigger an organism to become sexually mature. They may be external, such as drought (certain plants), or internal, such as percentage of body fat (certain animals). (Such internal cues are not to be confused with hormones, which directly produce sexual maturity – the production/release of those hormones is triggered by such cues.) Role of reproductive organs Sexual maturity is brought about by a maturing of the reproductive organs and the production of gametes. It may also be accompanied ...

Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams, where fresh water is running, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species, such as ''Procambarus clarkii'', are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' (Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crabs
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Grenadier
The blue grenadier (also known as hoki, blue hake, New Zealand whiptail, or whiptail hake, ''Macruronus novaezelandiae'') is a merluccid hake of the family Merlucciidae found around southern Australia and New Zealand, as well as off both the Atlantic and Pacific coasts of South America from Peru to Brazil at depths of between . It feeds in midwater on small squids, crustaceans, and fish. Its length is between . It is a slender, silvery fish similar in appearance to the gemfish. The meat of the fish is white and almost always sold in fillets; culinarily it is considered a whitefish. Commercial use Australian supermarkets have many hoki products, mainly in pre-packaged processed foods. Often the manufactured meat result is manufactured into a fish cutlet shape and then battered or crumbed to further give a good fresh look. The hoki is one of the species used in McDonald's Filet-O-Fish, Fish Fingers and McFish sandwiches. It was previously served at Long John Silver's and Denny's ...

Blue Cod
The New Zealand blue cod (''Parapercis colias'') is a temperate marine fish of the family Pinguipedidae. It is also known variously as Boston blue cod, New Zealand cod, sand perch, or its Māori names rāwaru, pākirikiri and patutuki. It is exclusively found in New Zealand in shallow waters around the rocky coasts to a depth of 150 m, though it is far more common south of Cook Strait. It is bluish green to blue-black above with white toward the belly. Large examples are usually greenish blue in colour, while smaller ones are blotched in varying shades of brown. An adult may grow to 60 cm in length and weigh from 1.0 to 3.0 kg. It feeds mainly on small fish and crabs. Blue cod is territorial. Spawning takes place in southern spring. Blue cod can also change sex from female to male. It is an important recreational species in the South Island and is commercially harvested. Blue cod populations are managed under New Zealand's fisheries quota management system, although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...
