Opisthoproctidae
Barreleyes, also known as spook fish (a name also applied to several species of chimaera), are small deep-sea argentiniform fish comprising the family Opisthoproctidae found in tropical-to-temperate waters of the Atlantic, Pacific, and Indian Oceans. These fish are named because of their barrel-shaped, tubular eyes, which are generally directed upwards to detect the silhouettes of available prey; however, the fish are capable of directing their eyes forward, as well. The family name Opisthoproctidae is derived from the Greek words ''opisthe'' 'behind' and ''proktos'' 'anus'. Description The morphology of the Opisthoproctidae varies between three main forms: the stout, deep-bodied barreleyes of the genera '' Opisthoproctus'' and '' Macropinna'', the extremely slender and elongated spookfishes of the genera '' Dolichopteryx'' and '' Bathylychnops'', and the intermediate fusiform spookfishes of the genera '' Rhynchohyalus'' and '' Winteria''. All species have large, telescoping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Symmetry in biology#Bilateral symmetry, bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and th ...

Chordata
A chordate () is an animal of the phylum Chordata (). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit metameric segmentation. In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels (CSIs) in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cephalochordates. These CSIs provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Act ...

Argentiniformes
The Argentiniformes are an order of ray-finned fish whose distinctness was recognized only fairly recently. In former times, they were included in the Osmeriformes (typical smelt and allies) as suborder Argentinoidei. That term refers only to the suborder of marine smelts and barreleyes in the classification used here, with the slickheads and allies being the Alepocephaloidei. These suborders were treated as superfamilies Argentinoidea and Alepocephaloidea, respectively, when the present group was still included in the Osmeriformes. They contain six or seven families with almost 60 genera and at least 228 species. A common name for the group is marine smelts and allies, but this is rather misleading since the "freshwater" smelts of the Osmeridae also live predominantly in the ocean.FishBase (2006)Order Osmeriformes Version of 2006-OCT-09.

Daniel Morris Cohen
Daniel Morris Cohen (6 July 1930 - 26 September 2016) was an American ichthyologist who was known for his studies on the taxonomy of salmonid, gadid, and ophidiform fishes. Cohen mainly studied the taxonomy of deep-sea fishes in the orders Salmoniformes, Gadiformes, and Ophidiformes. He held the post of professor of biology at the University of Florida The University of Florida (Florida or UF) is a public land-grant research university in Gainesville, Florida. It is a senior member of the State University System of Florida, traces its origins to 1853, and has operated continuously on its ... for one year. He then took an appointment at the U.S. Bureau of Commercial Fisheries Ichthyological Laboratory in Washington, D.C. as a systematic zoologist. He stayed there for 23 years before moving to California to become the Chief Curator of Life Sciences at the Natural History Museum of Los Angeles County.

Albert Eide Parr
Albert Eide Parr (15 August 1900 – 16 July 1991) was a Norwegian-born, American marine biologist, zoologist and oceanographer. He was the director of the American Museum of Natural History from 1942 to 1959. '' Parrosaurus missouriensis'', a species of plant-eating dinosaur, is named after him. Biography Albert Eide Parr was born and grew up in Bergen, Norway. His father, Thomas Johannes Lauritz Parr, was a professor at Bergen Cathedral School. He became well acquainted with Jørgen Brunchorst, director at the Bergen Museum and developed an early interest in marine biology. He studied at the University of Oslo (1921–24) and became cand.mag. in 1925. He worked was an assistant in zoology at the Bergen Museum from 1924–26. He and his wife traveled to the United States in 1926 where Parr is said to have first found work "sweeping floors" at the New York Aquarium in New York City. In 1927, he met American financier and philanthropist Harry Payne Bingham. They launched a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikolai Vasilyevich Parin
Nikolai Vasilyevich Parin (21 November 1932 – 18 April 2012) was a Soviet and Russian ichthyologist, specializing in oceanic pelagic fish. He headed the Laboratory of Oceanic Ichthyofauna at the RAS Institute of Oceanology in Moscow, where he ended his career as a Professor after more than fifty-seven years. In his career, he described more than 150 new taxa of fish and participated in 20 major oceanic expeditions. Thirty-six species of fish are named in his honour. Personal life Parin was born in Perm on 21 November 1932. His father was Vasily Vasilevich Parin, who was the founder and first Secretary General of the USSR Academy of Medicine but later was made politically suspect due to a trip to the United States and a dispute with Trofim Lysenko. After the death of Stalin in 1953 and rise of Khrushchev, his father was rehabilitated and played a key medical role in the Soviet space program. Because of his father's imprisonment, Parin could not study physics at Moscow Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
