Rostroraja Velezi
''Rostroraja'' is a genus of skate belonging to the family Rajidae, native to the Atlantic Ocean and East Pacific, including the Mediterranean, Caribbean, Gulf of Mexico and Gulf of California. The genus was considered monotypic in the past (containing only '' R. alba''), but a number of species usually classified in ''Raja'' have been reassigned to this genus based on genetic analysis.Last, P.

Rostroraja Texana
The roundel skate or Texas clearnose skate (''Rostroraja texana'') is a species of cartilaginous fish in the family Rajidae. It is found in the Gulf of Mexico, Southeast Florida and the Yucatan Peninsula. Description The disc of the roundel skate is diamond-shaped. The short rounded snout has a clear area of skin on either side. The rest of the dorsal surface is an unblotched chocolate brown colour, although sometimes there are darker patches. A pair of distinctive dark eyespots with pale pink rims lie on either side of the middle of the dorsal surface (these may confuse potential predators). A row of thorns runs along the midline of the back, but there are no venomous spines. The medium-length tail has a short dorsal fin near its tip and a small caudal fin. Males become mature at about 5 years old at a length of about , while females are mature a year later at a length of about . Distribution and habitat The roundel skate is native to the southeastern coast of Florida, the Gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rostroraja Alba
The bottlenose skate, spearnose skate, or white skate (''Rostroraja alba'') is a species of skate in the family Rajidae. It is a benthic fish native to the coastal eastern Atlantic Ocean. Due to overfishing, it has been depleted or extirpated in many parts of its former range in the northeastern Atlantic and the Mediterranean Sea, and is now endangered. Distribution and habitat The bottlenose skate is found along the coastlines of the eastern Atlantic Ocean, from the southern British Isles to South Africa and extends into the southwestern Indian Ocean to Mozambique. It is present as well in the western and northeastern sectors of the Mediterranean Sea. It is a benthic species of sandy and detrital bottoms, at depths of 40–400 m (exceptionally down to 500 m) from coastal regions to the upper continental slope. (1974) reported that it is more prevalent in rocky habitats. Description Most bottlenose skates are 60–150 cm long, with maximum recorded lengths of 230 cm ...

Charles Harvey Bollman
Charles Harvey Bollman (1868–1889) was an American naturalist who published on fishes and myriapods, becoming known internationally for his work in a short career before dying at the age of 20, considered by David Starr Jordan one of the most brilliant and promising naturalists he had ever known. Bollman was born in Monongahela, Pennsylvania, December 24, 1868. He attended the Indiana University at Bloomington where he studied under John C. Branner and David Starr Jordan. Bollman was a founding member of the university's Independent Literary Society. He graduated in June 1889 and was appointed immediately after as an assistant in the United States Fish Commission, and died of dysentery contracted while collecting fish in the Okefenokee Swamp of Waycross, Georgia, on July 13. He was the only 19th-century ichthyologist to enter the Okefenokee. Bollman published thirteen papers between the years of 1887 and 1889, including papers co-authored with Jordan. Of myriapods, he descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Louis Augustin Guillaume Bosc
Louis Augustin Guillaume Bosc (or Louis-Augustin Bosc d'Antic) (29 January 1759 – 10 July 1828) was a French botanist, invertebrate zoologist, and entomologist. Biography Bosc was born in Paris, the son of Paul Bosc d’Antic, a medical doctor and chemist. He studied at Dijon, where he was the pupil of botanist Jean-François Durande and chemist Louis-Bernard Guyton-Morveau. Being unable to become an artilleryman, he worked initially for the office of the controller general and then for the comptroller of the postal service. In time he took courses in botany under Antoine-Laurent de Jussieu and met botanist René Desfontaines and naturalist Pierre Marie Auguste Broussonet. He also took up with Jean Marie Roland and Madame Roland and formed a lasting relationship with Danish entomologist Johan Christian Fabricius. While working for the postal service he carried out work on natural history, publishing a description of a new species of fly, Orthezia characais, and a method of pr ...

Rostroraja Eglanteria
The clearnose skate (''Rostroraja eglanteria'') is a species of cartilaginous fish in the family Rajidae. ''R. eglanteria'' is also known by other common names such as the brier skate and summer skate. Clearnose skates are easily identified by the translucent patches on either side of their snouts and their mottled dorsal surface. They are found along the Atlantic and Gulf coasts of the United States in shallow waters of the continental shelf. Taxonomy Clearnose skates are elasmobranchs in the order Rajiformes and family Rajidae. They were one of nearly thirty members of the genus ''Raja'' before redesignation based on DNA analysis in 2016. Clearnose skates were first described as ''Raja eglanteria'' by Bosc in 1800. Other scientific names include ''R. chantenay'', ''R. desmarestia,'' and ''R. diaphanes;'' however, these names rarely appear in the literature. Description Clearnose skates are named for the characteristic light-colored to translucent patches along both sides ... [...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''.
