Exoglossum
''Exoglossum'' is a genus of mound-building freshwater fish of the minnow family ( Cyprinidae) containing two species, commonly known as cutlip minnows, although the individual species, particularly ''Exoglossum maxillingua'', are also locally known by that name. Species of this genus usually range from 3 inches to 18 inches when sexually mature. In many areas these minnows are valued as both panfish and baitfish. Species * ''Exoglossum laurae'' ( C. L.

Cutlips Minnow
:''"Cutlips minnows" is also used for the genus ''Exoglossum'' as a whole.'' ''Exoglossum maxillingua'' (cutlips minnow) is an olive-green medium-sized minnow (average 6 inches) of North America with a distinguishing lower jaw. Isolated from all other minnows by its three-lobed lower jaw with the middle lobe sticking out like a tongue. The range of this species is from the St. Lawrence and Lake Ontario south into Virginia. It is listed as "threatened" in the Canadian province of Ontario, but may never have been common there as this is the most northerly of its range. It is found in running streams and seems to prefer clear, stony pools but not rapids. The distinctive mouth of the cutlips lets it feed on minuscule shellfish which it scrapes from rocks. Although molluscs appear to be its primary food, it also eats insect larvae and diatoms. An interesting feeding behavior of this species is "eye-picking" when food is scarce or competition is high. The Cutlips will pluck ou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exoglossum Laurae
''Exoglossum laurae'' (common name tonguetied minnow) is a species of minnow found in North America. Description The color of the fish ranges from dark gray to brown-black, with purple specks located throughout its body and a white belly. The fish ranges from three to five inches long. The minnow is named for its mouth. The lower mouth is only partially covered with its lips, leaving part of the minnow's jaw exposed. The mouth is horizontal and small. The minnow has eight dorsal fin-rays, seven anal fin-rays, eight pelvic fin-rays and thirteen to seventeen pectoral fin-rays. Habitat The minnow lives throughout Ontario and the Northeastern United States. In the state of Ohio, the minnow is only confirmed to inhabit the Great Miami and Little Miami rivers. The Ohio population of ''Exoglossum laurae'', which is separated from more Eastern populations by several hundred miles, is considered a subspecies. The minnow is unable to live in murky waters and requires a clean rock river ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyprinidae
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 ...

Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; October 22, 1783September 18, 1840) was a French 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community whose submissions were rejected automatically by leading journals. Among his theories were th ...

Panfish
The word panfish, also spelled pan-fish or pan fish, is an American English term describing any edible freshwater fish that usually do not outgrow the size of an average frying pan. It is also commonly used by recreational anglers to refer to any small catch that can fit wholly into a pan but still large enough to be legal. The fish species which match this definition and usage vary according to geography. According to the Oxford English Dictionary, the term was first recorded in 1796 in ''American Cookery'', the first known cookbook written by an American author. __TOC__ Usage The term ''panfish'' or ''pan-fish'' has been used to refer to a wide range of edible freshwater and saltwater fish species that are small enough to cook whole in one frying pan. One early-20th-century source identifies all the following as panfish: yellow perch, candlefish, balaos, sand launces, rock bass, bullheads, minnows, Rocky Mountain whitefish, sand rollers, crappie, yellow bass, white bass ...

Carl Leavitt Hubbs
Carl Leavitt Hubbs (October 19, 1894 – June 30, 1979) was an American ichthyologist. Biography Youth He was born in Williams, Arizona. He was the son of Charles Leavitt and Elizabeth (née Goss) Hubbs. His father had a wide variety of jobs (farmer, iron mine owner, newspaper owner). The family moved several times before settling in San Diego where he got his first taste of natural history. After his parents divorced in 1907, he lived with his mother, who opened a private school in Redondo Beach, California. His maternal grandmother Jane Goble Goss, one of the first female doctors, showed Hubbs how to harvest shellfish and other sea creatures. One of his teachers, impressed by Hubbs's abilities in science, recommended that he study chemistry at the University of Berkeley. The family moved once more to Los Angeles. In Los Angeles, George Bliss Culver, one of the many volunteers of David Starr Jordan, encouraged Hubbs to abandon his study of birds and instead to study fish, par ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Freshwater
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Baitfish
300px, Feeder Goldfish are common baitfish. Bait fish (or baitfish) are small-sized fish caught and used by anglers as bait to attract larger predatory fish, particularly game fish. Baitfish species are typically those that are common and breed rapidly, making them easy to catch and in abundant supply. Overview Examples of marine bait fish are anchovies, gudgeon, halfbeaks such as ballyhoo, and scad. Some larger fish such as menhaden, flying fish or ladyfish may be considered bait fish in some circles, depending on the size of the gamefish being pursued. Freshwater bait fish include minnows from the carp family ( Cyprinidae), sucker family (Catostomidae), topminnows from the killifish suborder (Cyprinodontoidei), shad family (Clupeidae), sculpin of the order Scorpaeniformes and sunfish family (Centrarchidae), excluding black basses and crappies. Bait fish can be contrasted with forage fish. ''Bait fish'' is a term used particularly by recreational fishermen, although ...
