Fenestraja Plutonia
''Fenestraja plutonia'' is a species of cartilaginous fish in the family Gurgesiellidae. It is commonly known as the underworld windowskate or Pluto pygmy skate. The underworld windowskate is known from patches of continental slope in the western Atlantic Ocean between the coasts of the southern United States and Suriname. Etymology The underworld windowskate's genus name, ''Fenestraja'', comes from a combination of two words. is a Latin word meaning window, which in this case refers to a small opening in bone.Romero, P., 2002. An etymological dictionary of taxonomy. Madrid, unpublished. A second Latin word, ''Raja'' simply refers to the genus as a skate (fish), skate/ray of the family Rajidae. Its species name is a reference to Pluto (mythology), Pluto (, ) the Greek mythology, Greek god of the Greek underworld, underworld.William Hansen, Classical Mythology: A Guide to the Mythical World of the Greeks and Romans.

Batoidea
Batomorphi is a Division (taxonomy), division of Chondrichthyes, cartilaginous fishes, commonly known as rays, this taxon is also known as the Order (biology), superorder Batoidea, but the 5th edition of ''Fishes of the World'' classifies it as the division Batomorphi. They and their close relatives, the sharks, compose the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces. Anatomy Batomorphs are flat-bodied, and, like sharks, are cartilaginous fish, meaning they have a boneless skeleton made of a tough, elastic cartilage. Most batomorphs have five ventral slot-like body openings called gill slits that lead from the gills, but the Hexatrygonidae have six. Batomorph gill slits lie under the pectoral fins on the underside, whereas a shark's are on the sides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manganese Nodule
Polymetallic nodules, also called manganese nodules, are mineral concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as a potential economic interest. Depending on their composition and authorial choice, they may also be called ferromanganese nodules. Ferromanganese nodules are mineral concretions composed of silicates and insoluble iron and manganese oxides that form on the ocean seafloor and terrestrial soils. The formation mechanism involves a series of redox oscillations driven by both abiotic and biotic processes. As a byproduct of pedogenesis, the specific composition of a ferromanganese nodule depends on the composition of the surrounding soil. The formation mechanisms and composition of the nodules allow for couplings with biogeochemical cycles beyond iron and manganese. The high relative abundance of nickel, cop ...

Fernando De Buen Y Lozano
Fernando de Buen y Lozano (10 October 1895 – 6 May 1962) was a Spanish ichthyologist and oceanographer. He lived in Mexico, Uruguay, and Chile. In Uruguay, he was the director of the Department of Science at the Oceanography and Fisheries Service as well as Professor of Hydrobiology and Protozoology in the Faculty of Arts and Sciences.

Chondrichthyes
Chondrichthyes (; ) is a class of jawed fish that contains the cartilaginous fish or chondrichthyans, which all have skeletons primarily composed of cartilage. They can be contrasted with the Osteichthyes or ''bony fish'', which have skeletons primarily composed of bone tissue. Chondrichthyes are aquatic vertebrates with paired fins, paired nares, placoid scales, conus arteriosus in the heart, and a lack of opercula and swim bladders. Within the infraphylum Gnathostomata, cartilaginous fishes are distinct from all other jawed vertebrates. The class is divided into two subclasses: Elasmobranchii (sharks, rays, skates and sawfish) and Holocephali ( chimaeras, sometimes called ghost sharks, which are sometimes separated into their own class). Extant chondrichthyans range in size from the finless sleeper ray to the over whale shark. Anatomy Skeleton The skeleton is cartilaginous. The notochord is gradually replaced by a vertebral column during development, e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Henry Bryant Bigelow
Henry Bryant Bigelow (October 3, 1879 – December 11, 1967) was an American oceanographer and marine biologist. He was a professor at Harvard University for 60 years and was the founding director of the Woods Hole Oceanographic Institution. The U.S. research vessel ''NOAAS Henry B. Bigelow'' was named in his honor. Life and career He was the grandson of Henry Bryant who was an American physician and naturalist. After graduating from Harvard in 1901, he began working with famed ichthyologist Alexander Agassiz. Bigelow accompanied Agassiz on several major marine science expeditions including one aboard the ''Albatross'' in 1907. He began working at the Museum of Comparative Zoology in 1905 and joined Harvard's faculty in 1906 where he worked for 62 years. In 1911, Bigelow was elected a Fellow of the American Academy of Arts and Sciences. He helped found the Woods Hole Oceanographic Institution in 1930 and was its founding director. He was elected to the United States Nation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Charles Schroeder
William Charles Schroeder (1895–1977) was an American ichthyologist. He was born on Staten Island, New York. He, along with his lifelong colleague Henry Bryant Bigelow, made substantial contributions to the knowledge of the fish fauna of the western North Atlantic. The two described 42 new species of jawless fishes and cartilaginous fishes, and authored several seminal publications, including ''Fishes of the Western North Atlantic'' and ''Fishes of the Gulf of Maine''.
