Zaniolepis
''Zaniolepis'', the combfishes, is a genus of marine ray-finned fish, it is one of two genera in the family Zaniolepididae. These fishes are native to the eastern Pacific Ocean. ''Z. frenata'' that was a source of food to the Native American inhabitants of San Nicolas Island off the coast of southern California, United States during the Middle Holocene.Vellanoweth, R. L. & Erlandson, J. M. (1999)Middle Holocene Fishing and Maritime Adaptations at CA-SNI-161, San Nicolas Island, California.''Journal of California and Great Basin Anthropology, 21(2): pp. 257-274'' Taxonomy ''Zaniolepis'' was first proposed as a monospecific genus in 1858 by the French zoologist Charles Frédéric Girard when he described ''Z. longispinis'' from Fort Steilacoom on Puget Sound in Washington. This genus is one of two genera in the family Zaniolepidae, each of which is classified within a monotypic subfamily. The subfamily Zaniolepinae, along with the Oxylebiinae, haves been classified as two su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zaniolepis Frenata
''Zaniolepis frenata'', also known as the shortspine combfish, is a species of ray-finned fish belonging to the family Zaniolepididae.The species occurs in the eastern Pacific Ocean. Taxonomy ''Zaniolepis frenata'' was first formally described in 1889 by the American ichthyologists Carl H. Eigenmann and Rosa Smith Eigenmann with its type locality given as Cortes Bank off San Diego, California. The specific name, ''frenata'', means "bridled". The Eigenmanns did not explain this allusion but they were probably referring the diagonal dark band running through the eye. Description ''Zaniolepis frenata'' has an elongated, slender and compressed body. The background color is tan or pink on the upper body broken by with darker, rather ill-defined markings, fading to white on the underside. In life they have a row of dark saddle-like markings along the back and a variety of blotches and spots on the flanks with a diagonal dark bar through the eye. They have a long anal fin which has ...

Zaniolepis Latipinnis
''Zaniolepis latipinnis'', the longspine combfish or longspined greenling, is a species of ray-finned fish belonging to the family Zaniolepididae.The species occurs in the eastern Pacific Ocean. Taxonomy ''Zaniolepis latipinnis'' was first formally described in 1858 by the French biologist Charles Frédéric Girard with its type locality given as Fort Steilacoom on Puget Sound in Washington. Girard placed his new species in a new monospecific genus, ''Zaniolepis''. The specific name, ''latipinnis'', means "broad-finned", a reference to the long bases of the dorsal and anal fins. Description ''Zaniolepis latipinnis'' has a slender, elongated and compressed body which is covered in small, rough scales. The head is of moderate length with a small terminal mouth and eyes that are positioned high on the head. There are 21 or 22 spines in the first dorsal fin, the first 3 spines being very elongated, with 11 or 12 soft rays in the second dorsal fin. The anal fin has 3 spines and betw ...

Zaniolepididae
The Zaniolepididae is a Family (biology), family of marine ray-finned fishes classified within the suborder Cottoidei of the Order (biology), order Perciformes. They are found in the North Pacific Ocean. Taxonomy ''Zaniolepididae'' was first proposed as a family in 1883 by the American ichthyologists David Starr Jordan and Charles Henry Gilbert. this taxon has been classified as the subfamily Zaniolepinae within the Hexagrammidae. This family is classified within its own Superfamily (biology), superfamily, the Zaniolepidoidea, within the suborder Cottoidei of the Scorpaeniformes. Other workers have found that if the Scorpaeniformes, as delimited in ''Fishes of the World'', is not included in the Perciformes it renders the Perciformes paraphyletic. These workers retain the Cottoidei as a suborder within the Perciformes while reclassifying Zaniolepidoidea as the infraorder Zaniolepidoales. Subfamilies and genera Zaniolepididae has 2 genera classified within it, each within its own ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxylebiinae
The painted greenling (''Oxylebius pictus'') is a species of marine ray-finned fish belonging to the family Zaniolepididae, which includes this species and the combfishes. It is endemic to the northeast Pacific Ocean. It is the only species in the genus ''Oxylebius''. Taxonomy The painted greenling was first formally described in 1862 by the American biologist Theodore Gill with the type locality given as San Francisco. Gill classified it in the monospecific genus ''Oxylebius'' and proposed the monotypic subfamily Oxylebinae which was placed in the family Hexagrammidae, although the subfamily was placed in the Zaniolepididae in the 6th edition of ''Fishes of the World'' and other authorities. Etymology The painted greenling's generic name ''Oxylebius'' prefixes ''oxy'' meaning "sharp", alluding to the sharper snout of this species in comparison to ''Zaniolepis'', to ''lebius'' which Gill did not explain. However Jordan and Evermann gave their view that ''lebius'' is a Synon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpaeniformes Genera
The Scorpaeniformes are a diverse order of ray-finned fish, including the lionfishes and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320. They are known as "mail-cheeked" fishes due to their distinguishing characteristic, the suborbital stay: a backwards extension of the third circumorbital bone (part of the lateral head/cheek skeleton, below the eye socket) across the cheek to the pre operculum, to which it is connected in most species. Scorpaeniform fishes are carnivorous, mostly feeding on crustaceans and on smaller fish. Most species live on the sea bottom in relatively shallow waters, although species are known from deep water, from the midwater, and even from fresh water. They typically have spiny heads, and rounded pectoral and caudal fins. Most species are less than in length, but the full size range of the order varies from the velvetfishes belonging to the family Aploactini ...

Puget Sound
Puget Sound ( ; ) is a complex estuary, estuarine system of interconnected Marine habitat, marine waterways and basins located on the northwest coast of the U.S. state of Washington (state), Washington. As a part of the Salish Sea, the sound (geography), sound has one major and two minor connections to the Strait of Juan de Fuca, which in turn connects to the open Pacific Ocean. The major connection is Admiralty Inlet; the minor connections are Deception Pass and the Swinomish Channel. Puget Sound extends approximately from Deception Pass in the north to Olympia, Washington, Olympia in the south. Its average depth is and its maximum depth, off Jefferson Point between Indianola, Washington, Indianola and Kingston, Washington, Kingston, is . The depth of the main basin, between the southern tip of Whidbey Island and Tacoma, Washington, Tacoma, is approximately . In 2009, the term Salish Sea was established by the United States Board on Geographic Names as the collective wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene Fish
The Pleistocene ( ; referred to colloquially as the ''Ice Age'') is the geological epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold glacial periods and warmer interglacials, with the sea levels being up to lower than ...

Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral (belly) surface of fish, and are the lower of the only two sets of paired fins (the other being the laterally positioned pectoral fins). The pelvic fins are homologous to the hindlimbs of tetrapods, which evolved from lobe-finned fish during the Middle Devonian. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays ( lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Rosa Smith Eigenmann
Rosa Smith Eigenmann (October 7, 1858 – January 12, 1947) was an American ichthyologist (the branch of zoology devoted to the study of fish), as well as a writer, editor, former curator at the California Academy of Sciences, and the first librarian of the San Diego Society of Natural History. She "is considered the first woman ichthyologist in the United States." Eigenmann was also the first woman to become president of Indiana University's chapter of Sigma Xi, an honorary science society. She authored twelve published papers of her own between 1880 and 1893, and collaborated with her husband, Carl H. Eigenmann, as "Eigenmann & Eigenmann" on twenty-five additional works between 1888 and 1893. Together, they are credited with describing about 150 species of fishes. Early life and education Rosa Smith was born on October 7, 1858, in Monmouth, Illinois, the youngest of Lucretia (Gray) and Charles Kendall Smith's nine children. Smith's parents, originally from Vermont, had move ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
