Alaska Blackfish
The Alaska blackfish (''Dallia pectoralis'') is a species of freshwater fish in the esocid family (Esocidae) of order Esociformes. It inhabits Arctic regions of Alaska as well as Siberia and the Bering Sea islands. Description Alaska blackfish are small, with an average length of , but have been known to reach . They have an easily distinguishable morphology (a branch of biology dealing with the study of the form and structure of organisms and their specific structural features), with relatively large, posterior dorsal fin and anal fins, large, lobed pectoral fins located just posterior to the operculum, a diphycercal caudal fin, and small, pointy pelvic fins. The head is broad and flat, with the trunk being long and slender. The color is dark green to brown on the dorsal side, pale below, with light-colored blotches appearing laterally. Males can be distinguished from females by the presence of a reddish fringe along the dorsal, caudal, and anal fins; also, the tips of the ...

River Blackfish
The river blackfish (''Gadopsis marmoratus'') is a freshwater fish endemic to the temperate waters of south-eastern Australia. It is found from southern Queensland through to central Victoria, including in the Murray- Darling river system. It is also found in some eastern and southern flowing coastal rivers. Found primarily in upland and "midland" habitats, though early records of fish fauna suggest it was originally far more extensively distributed and was found in some lowland habitats as well. Originally, river blackfish co-inhabited many of its lowland and "midland" habitats with species such as Murray cod and golden perch, and its upland habitats with species such as trout cod and Macquarie perch. It is a popular angling fish in some parts of its range. Description River blackfish are elongated with a rounded body, distinct snout and large mouth, and small to moderate sized eyes. The caudal fin, soft dorsal fin and anal fin are rounded. The spiny dorsal fin is low, we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacramento Blackfish
The Sacramento blackfish (''Orthodon microlepidotus'') is a species of freshwater fish in central California. A cyprinid, the blackfish is the sole member of its genus. Distribution and habitat Blackfish are primarily denizens of the warm and cloudy waters found on the floor of the Central Valley, such as sloughs and oxbow lakes connected to the Sacramento and San Joaquin Rivers. They are also common in Clear Lake, Pajaro River, Salinas River, the small creeks that feed into San Francisco Bay. A population is present in the Russian River, believed to have been introduced. They also thrive in reservoirs, and have been spread to a number of California reservoirs via the California Aqueduct, and into Nevada via the Lahontan Reservoir (1964) where they have further colonized the Humboldt River drainage.

Two-spined Blackfish
The two-spined blackfish (''Gadopsis bispinosus'') is a species of temperate perch endemic to Australia. It is found in the cool, clear, strong-flowing, cobble bottomed, sub-alpine rivers and streams (ranging from small to large) in the southeast corner of the Murray- Darling river system. Their range encompasses northeast Victoria, southeast New South Wales and the Australian Capital Territory. Originally two-spined blackfish co-inhabited many of these waters with Macquarie perch and trout cod. Two-spined blackfish are similar in shape and appearance to river blackfish, though their spiny dorsal fin usually contain only two spines (hence their scientific name) in comparison to river blackfish which have 7 to 13 distinguishable spines in their spiny dorsal fin. (In reality, this is a rather academic point as two-spined blackfish have blurred the difference between the dorsal spines and the dorsal rays that make up their soft dorsal fin, and any distinctions between the two we ...

Many-toothed Blackfish
The melon-headed whale (''Peponocephala electra''), also known less commonly as the electra dolphin, little killer whale, or many-toothed blackfish, is a toothed whale of the oceanic dolphin family (Delphinidae). The common name is derived from the head shape. Melon-headed whales are widely distributed throughout deep tropical and subtropical waters worldwide, but they are rarely encountered at sea. They are found near shore mostly around oceanic islands, such as Hawaii, French Polynesia, and the Philippines. Taxonomy The melon-headed whale is the only member of the genus ''Peponocephala''. First recorded from a specimen collected in Hawaiʻi in 1841, the species was originally described as a member of the dolphin family and named ''Lagenorhynchus electra'' by John Edward Gray in 1846. The melon-headed whale was later determined to be sufficiently distinct from other ''Lagenorhynchus'' species to be accorded its own genus. A member of the subfamily Globicephalinae, melon-headed wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Blackfish
The imperial blackfish, ''Schedophilus ovalis'', is a medusafish of the family (biology), family Centrolophidae found in the eastern Atlantic and the Mediterranean Sea, and occasionally western Atlantic (Bermuda). It occurs at depths of between 70 and 700 m. In its juvenile stage it is often found finding shelter amongst of the tentacles of floating jellyfish, including the Portuguese man o' war. It grows to Fish measurement, total length.

Gadopsis
''Gadopsis'' is a genus of temperate perches endemic Endemism is the state of a species being found 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 found else ... to freshwater habitats in southeastern Australia. The genus was formerly considered to be in a family of its own, Gadopsidae. Species There are two species in this genus: * '' Gadopsis bispinosus'' Sanger, 1984 (Two-spined blackfish) * '' Gadopsis marmoratus'' J. Richardson, 1848 (River blackfish) References Percichthyidae Taxa named by John Richardson (naturalist) Freshwater fish genera {{Perciformes-stub ...

Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Pilot Whale
Pilot whales are cetaceans belonging to the genus ''Globicephala''. The two extant species are the long-finned pilot whale (''G. melas'') and the short-finned pilot whale (''G. macrorhynchus''). The two are not readily distinguishable at sea, and analysis of the skulls is the best way to distinguish between the species. Between the two species, they range nearly worldwide, with long-finned pilot whales living in colder waters and short-finned pilot whales living in tropical and subtropical waters. Pilot whales are among the largest of the oceanic dolphins, exceeded in size only by the orca. They and other large members of the dolphin family are also known as blackfish. Pilot whales feed primarily on squid, but will also hunt large demersal fish such as cod and turbot. They are highly social and may remain with their birth pod throughout their lifetime. Short-finned pilot whales are one of the few mammal species in which females go through menopause, and postreproductive females ...

Tautoga Onitis
The tautog (''Tautoga onitis''), also known as the blackfish, is a species of wrasse native to the western Atlantic Ocean from Nova Scotia to South Carolina. This species inhabits hard substrate habitats in inshore waters at depths from . It is currently the only known member of its genus. Barlett (1848) wrote, " autaugis a Native American word, and may be found in Roger Williams' ''Key to the Indian Language''." The name is from the Narragansett language, originally ''tautauog'' (pl. of ''taut''). It is also called a "black porgy" (''cf.'' Japanese black porgy), "chub" (''cf.'' the freshwater chub), "oyster-fish" (in North Carolina) or "blackfish" (in New York/New Jersey, New England). Description Tautog are brown and dark olive, with white blotches, and have plump, elongated bodies. They have an average weight of and reach a maximum length and weight of and respectively. Tautog have many adaptations to life in and around rocky areas. They have thick, rubbery lips and powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Girella Tricuspidata
The parore (''Girella tricuspidata'') also known as luderick, black bream or blackfish is a species of marine ray-finned fish, a sea chub from the family Kyphosidae which is found in the southwestern Pacific Ocean off Australia and New Zealand. Parore or paraore is the common name in New Zealand but in Australia luderick is preferred. Description The parore has a moderately deep, compressed, oval shaped body with a thin caudal peduncle, It has a small head which has a slightly convex forehead, and small eyes. The mouth is small and does not extend as far as the eye. The jaws have an outer row of overlapping, flattened, tricuspid teeth beside a wide band of teeth of similar shape but which are tiny. Much of the body is covered im moderately small ctenoid scales and there is an arched lateral line, made up of 48-51 pored scales, which is parallel to the dorsal profile. It has a continuous dorsal fin which has no demarcation between its spiny and rayed parts. The spiny part has 14-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
