Bajacalifornia
''Bajacalifornia'' is a genus of slickheads. It was described in 1925 by Charles Haskins Townsend and John Treadwell Nichols on the basis of ''Bajacalifornia burragei''Deep sea fishes of the ''Albatross'' Lower California Expedition. Bulletin of the AMNH ; v. 52, article 1 which was discovered in 1911 during the deep sea expedition of the research vessel USS Albatross off the coast of Todos Santos Bay at the Baja California peninsula. In 1952 Ichthyologist Albert Eide Parr published a revision of this genus.Albert Eide Parr:'' Revision of the Species Currently Referred to Alepocephalus, Halisauriceps, Bathytroctes und Bajacalifornia with Introduction of Two New Genera''. In: Bulletin of the Museum of Comparative Zoology at Harvard College Vol. 107 (4), 1952. Species There are currently six recognized species in this genus: * '' Bajacalifornia aequatoris'' Miya & Markle, 1993 * '' Bajacalifornia arcylepis'' Markle & G.

Isla Todos Santos
Isla Todos Santos is a pair of islands about off Ensenada, Baja California, at best known for surfing. Access is only by boat, which can be rented in Ensenada, or La Bufadora. The waves off the smallest island are among the biggest in North America. There are no facilities on the islands except for two lighthouses and a fish farm operation. Fauna The islands are (or were) home to ''Aimophila ruficeps sanctorum'', an endemic Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also foun ... subspecies of the Rufous-crowned sparrow, which is probably extinct. It was previously home to Anthony's woodrat, which is now extinct. It is home to a critically endangered subspecies, the Todos Santos Island Kingsnake, of the California mountain kingsnake.

Slickhead
Slickheads, also known as nakedheads or smoothheads, are deep water fishes that belong to the family Alepocephalidae. They are most commonly found in the bathypelagic layer, which is approximately 3000m below the surface. They get their name from the lack of scales on their heads. Similarly, the scientific name is from the Greek ᾰ̓- (''a''-, "not"); λέπος (''lepos'', "scale"); and κεφαλή (''kephalē'', "head"). It has about 22 genera with ca. 96 species. The only known fossil genus is '' Carpathichthys'' from the Early Oligocene of Poland, although an undescribed species of ''Bathyprion'' and several indeterminate taxa are also known from the same formation. Fossil otoliths are also known, dating to the Early Eocene. Genera Alepocephalidae contains the following extant genera: * '' Alepocephalus'' Risso, 1820 * ''Asquamiceps'' Zugmayer, 1911 * ''Aulastomatomorpha'' Alcock, 1890 * ''Bajacalifornia'' Townsend & Nichols, 1925 * ''Bathylaco'' Goode & T.

Albert Eide Parr
Albert Eide Parr (15 August 1900 – 16 July 1991) was an 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 to 1926. 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 series of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Treadwell Nichols
John Treadwell Nichols (June 11, 1883 – November 10, 1958) was an American ichthyologist and Ornithology, ornithologist. Life and career Nichols was born in Jamaica Plain, Boston, Massachusetts, the son of Mary Blake (Slocum) and John White Treadwell Nichols. In 1906 he studied vertebrate zoology at Harvard College, where he graduated with a Bachelor of Arts (AB). In 1907 he joined the American Museum of Natural History as assistant in the department of mammalogy. In 1913 he founded ''Copeia'', the official journal of the American Society of Ichthyologists and Herpetologists. In 1916 he described the long lost Bermuda petrel together with Louis L. Mowbray, Louis Leon Arthur Mowbray who first sighted this bird within a flock of other petrels in 1906 on Castle Island, Bermuda 45 years before it was officially rediscovered by Mowbray's son Louis. He also described the fish genus ''Bajacalifornia''. He also worked with a team of scientists from the American Museum of Natural Histo ...

Gill Raker
Gill rakers in fish are bony or cartilaginous processes that project from the branchial arch (gill arch) and are involved with suspension feeding tiny prey. They are not to be confused with the gill filaments that compose the fleshy part of the gill used for gas exchange. Rakers are usually present in two rows, projecting from both the anterior and posterior side of each gill arch. Rakers are widely varied in number, spacing, and form. By preventing food particles from exiting the spaces between the gill arches, they enable the retention of food particles in filter feeders. The structure and spacing of gill rakers in fish determines the size of food particles trapped, and correlates with feeding behavior. Fish with densely spaced, elongated, comb-like gill rakers are efficient at filtering tiny prey, whereas carnivores and omnivores often have more widely spaced gill rakers with secondary projections. Because gill raker characters often vary between closely related taxa, they a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
