Harriotta Avia
''Harriotta avia'', the Australasian narrow-nosed spookfish, is a type of chimaera of the family Rhinochimaeridae identified from several specimens found in New Zealand, Southwest Pacific Ocean. Its distribution range is now believed to be New Zealand and Australia. Description ''Harriotta avia'' is distinguished from its congeners (''Harriotta raleighana'' and ''Harriotta haeckeli'') by several characteristics, including elongated slender trunk, slim rod-like pelvic claspers, dorsal spin going beyond the dorsal fin's apex, and long thin snout up to 56% of its body diagonal length. Its body color is mainly chocolate brownish if the skin is intact. This species maximum total length is around 107.5 cm for female specimens and 95.7 cm for male specimens. Distribution and habitat It is suggested that ''Harriotta avia'' lives at a depth of 260–1278 m, although 400–1000 m might be a closer possibility.

Chimaera
Chimaeras are Chondrichthyes, cartilaginous fish in the order (biology), order Chimaeriformes (), known informally as ghost sharks, rat fish (not to be confused with rattails), spookfish, or rabbit fish; the last two names are also applied to Barreleye, Opisthoproctidae and Rabbitfish, Siganidae, respectively. At one time a "diverse and abundant" group (based on the fossil record), their closest living relatives are sharks and ray (fish), rays, though their last common ancestor with them lived nearly 400 million years ago. Living species (aside from plough-nose chimaeras) are largely confined to deep water. Anatomy Chimaeras are soft-bodied, shark-like fish with bulky heads and long, tapered tails; measured from the tail, they can grow up to in length. Like other members of the class Chondrichthyes, chimaera skeletons are entirely cartilaginous, or composed of cartilage. Males use forehead denticles to grasp a female by a fin during copulation.

Rhinochimaeridae
The Rhinochimaeridae, commonly known as long-nosed chimaeras, are a family (biology), family of cartilaginous fish. They are similar in form and habits to other chimaeras, but have an exceptionally long conical or paddle-shaped snout. The snout has numerous sensory nerve endings, and is used to find food such as small fish. The first dorsal fin includes a mildly venomous spine, used in defense. Long-nosed chimaeras are found in temperate and tropical seas worldwide, from in depth. In August 2020, a long-nosed chimaera was brought up from off the Grand Banks of Newfoundland. They range from in maximum total length, depending on species. Species The eight known species are in three genera: Family Rhinochimaeridae * Genus ''Harriotta'' George Brown Goode, Goode & Tarleton Hoffman Bean, Bean, 1895 (Late Cretaceous to present) ** ''Harriotta haeckeli'' Karrer, 1972 (smallspine spookfish) ** ''Harriotta raleighana'' Goode & Bean, 1895 (narrownose chimaera) ** Harriotta avia, ...

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] |

Narrownose Chimaera
The narrownose chimaera (''Harriotta raleighana'') is a longnose chimaera of the family Rhinochimaeridae, the longnose chimaeras, consisting of eight species belonging three genera. This species is found in temperate seas worldwide, at depths between 200 and 3,100 m. Its length is between 1.0 and 1.5 m, including a long, tapering snout and a long, filamentous tail. Taxonomy This species was first described by George Brown Goode and Tarleton Hoffman Bean in 1895. The genus ''Harriotta'' refers to Thomas Harriot and the species name references Sir Walter Raleigh. Description Narrownose chimaeras have elongate rostra, slender tails, large pectoral and pelvic fins, large eyes, and two dorsal fins, the first being preceded by a mildly toxic spine. They possess two pairs of non-replaceable tooth plates in the upper jaw and a one pair in the lower jaw.Didier, Dominique A. "Phylogeny and classification of extant Holocephali."

Smallspine Spookfish
The smallspine spookfish (''Harriotta haeckeli'') is a species of fish in the family Rhinochimaeridae with a rather disjunct population. Its natural habitat is open seas. Taxonomy This species was first described by Christine Karrer in 1972. It has been hypothesised that some records of ''H. raleighana'' might refer to ''H. haeckeli''. This species is named in honor of both the research vessel ''Ernst Haeckel'', from which type was collected, and to the eminent zoologist Ernst Haeckel (1834–1919) for whom the ship was named. Description ''H. haeckeli'' is a small species compared to others in its genus and is coloured pale brown with darker shading on its underside. Distribution This species can be found off western Greenland, the Canary Islands, northeastern North America, Namibia, the southeastern Indian Ocean, Tasmania and southwestern New Zealand. It normally lives at depths greater than 1100 m. Conservation status This species is threatened by habitat loss. How ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harriotta
''Harriotta'' is a genus of cartilaginous fish in the family Rhinochimaeridae. The name honours Thomas Harriot (c.1560‒1621), English astronomer, mathematician, ethnographer and translator, who published the first English work on American natural history in 1588. Some common names for species in the genus include rabbitfish, spookfish and chimaera. Distribution ''Harriotta'' species can be found in the deep waters of continental slopes around 380 to 2,600 m deep in the Atlantic and the Pacific Oceans. It is also known to be found in the Indian Ocean off of southern Australia. They are also common in the northern Atlantic, northwest Pacific, and southwest Pacific Oceans.
