Halosaurus Pectoralis
The goanna fish, Australian halosaur, or common halosaur, ''Halosaurus pectoralis'', is a halosaur of the genus ''Halosaurus'', found in the south west Pacific Ocean The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continen ....

Allan Riverstone McCulloch
Allan Riverstone McCulloch (20 June 1885 – 1 September 1925) was a prominent Australian ichthyologist. Born in Sydney, Australia, McCulloch began his scientific career at the age of 13 as an unpaid assistant to Edgar Ravenswood Waite in the Australian Museum where Waite encouraged McCulloch to study zoology. Three years later, he was employed as a "mechanical assistant", and five years after that, as curator of fishes, a post he held until his death. McCulloch collected and published prolifically; from his first paper in 1906 (published in ''Records of the Australian Museum''), no year passed without his making a contribution to science, and he wrote over 100 original papers in all, many including his own illustrations. McCulloch travelled widely for his collections, including trips to Queensland, Lord Howe Island, New Guinea, the Great Barrier Reef and various Pacific islands. His major research interest was in fish, but he was also given the responsibility of the crustace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halosaur
Halosaurs are eel-shaped fishes found only at great ocean depths. As the family Halosauridae, halosaurs are one of two families within the order Notacanthiformes; the other being the deep-sea spiny eels, Notacanthidae. Halosaurs are thought to have a worldwide distribution, with some 17 species in three genera represented. Only a handful of specimens have been observed alive, all in chance encounters with Remotely operated underwater vehicles. The term "halosaur" refers to the type genus, ''Halosaurus'', which is a Greek compound word, ''hals'' meaning "sea" and ''sauros'' meaning "lizard". Halosaurs have a spotty fossil record, the oldest known genus being ''Echidnocephalus'' from the Late Cretaceous strata of Westphalia, Germany, and the second-oldest known genus, ''Laytonia'', from Miocene strata of California and Oregon. The fossil specimens already bear strong resemblance to the modern genera. The halosaurs' greatly elongated bodies end in whip-like tails; their scales are ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Deep Sea Fish
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic (1000–4000m deep) and abyssopelagic (4000–6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200–1000m deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of 700m and 1000m deep depending on the place in the ocean. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
