Phoxinus brachyurus, also known as the Seven River's minnow, is a species of freshwater fish in the family Cyprinidae. [1]
The Eurasian minnow, minnow, or common minnow is a small species of freshwater fish in the carp family Cyprinidae. It is the type species of genus Phoxinus. It is ubiquitous throughout much of Eurasia, from Britain and Spain to eastern Siberia, predominantly in cool streams and well-oxygenated lakes and ponds. It is noted for being a gregarious species, shoaling in large numbers.
Phoxinus is a genus of freshwater fish in the family Leuciscidae of order Cypriniformes, and the only members of the subfamily Phoxininae, or Eurasian minnows. The type species is Phoxinus phoxinus. The other species in this genus are also commonly known as minnows. The name "minnow" was what early English fisherman used to describe "small and insignificant". The genus Phoxinus is found throughout Eurasia, and includes 21 known species. Previously, members of the North American genus Chrosomus were also believed to form part of this genus.
In 1938, the Austrian ethologist Karl von Frisch made his first report on the existence of the chemical alarm signal known as Schreckstoff in minnows. An alarm signal is a response produced by an individual, the “sender”, reacting to a hazard that warns other animals, the receivers, of danger. This chemical alarm signal is only released when the sender incurs mechanical damage, such as when it has been caught by a predator, and is detected by the olfactory system. When this signal reaches the receivers, they perceive a greater predation risk and exhibit an antipredator response. Since populations of fish exhibiting this trait survive more successfully, the trait is maintained via natural selection. While the evolution of this signal was once a topic of great debate, recent evidence suggests schreckstoff evolved as a defense against environmental stressors such as pathogens, parasites, and UVB radiation and that it was later co-opted by predators and prey as a chemical signal.
The northern redbelly dace is a freshwater cyprinid fish, generally found in lakes and small streams in the northeastern United States and eastern Canada. Ranging from 1-3 inches, it is one of forty-four species from the minnow and carp family of Cyprinidae in these areas.
The copper shark, bronze whaler, or narrowtooth shark, is a species of requiem shark, family Carcharhinidae, and the only member of its genus found mostly at temperate latitudes. It is distributed in a number of separate populations in the northeastern and southwestern Atlantic, off southern Africa, in the northwestern and eastern Pacific, and around Australia and New Zealand, with scattered reports from equatorial regions. This species can be found from brackish rivers and estuaries, to shallow bays and harbors, to offshore waters 100 m (330 ft) deep or more. Females are found apart from males for most of the year, and conduct seasonal migrations. A large species reaching 3.3 m (11 ft) long, the copper shark is difficult to distinguish from other large requiem sharks. It is characterized by its narrow, hook-shaped upper teeth, lack of a prominent ridge between the dorsal fins, and plain bronze coloration.
In the British Isles, coarse fishing refers to angling for freshwater fish which are traditionally considered undesirable as a food or game fish. Freshwater game fish are all salmonids—most particularly salmon, trout and char—so generally coarse fish, also known as rough fish, are freshwater fish that are not salmonids. There is disagreement over whether grayling should be classified as a game fish or a coarse fish.
The short-tail lanternshark is a shark of the family Etmopteridae found in the western Pacific between latitudes 37°N and 30°S, at depths of between 450 and 900 m. Its length is up to 50 cm (20 in).
The minnow-nase, Serbo-Croatian: podbila, is a species of freshwater fish in the family Cyprinidae. It is found in Bosnia and Herzegovina and Croatia. Its natural habitats are rivers, intermittent rivers, and inland karsts. It is threatened by habitat loss and considered Endangered (EN).
The blackside dace ) is a species of ray-finned fish in the family Cyprinidae. It is endemic to the Cumberland River drainage in Kentucky and Tennessee as well as the Powell River drainage in Virginia in the United States. It is a federally listed threatened species.
The Tennessee dace is a species of ray-finned fish in the family Cyprinidae. It is found only in the United States; particularly in northeast Tennessee and southwest Virginia, and parts of extreme northwest Georgia. Until recently, they were considered a subspecies of mountain redbelly dace. They are commonly found in East Tennessee in spring fed first-order streams, often in silt and fine gravel pools, or undercut banks. These streams usually do not exceed two meters in width.
The laurel dace is a species of freshwater minnow native to the U.S. state of Tennessee. It was first discovered in 1976. A very rare species, it has only been found in localized populations in six small streams on the Walden Ridge portion of the Cumberland Plateau in Tennessee. It is found in six streams: the Soddy, Horn, Cupp, Young's, Moccasin, and Bumbee Creeks, all of which drain into larger rivers that eventually feed the Tennessee River. It is believed to be extirpated from Laurel Creek, the only other stream where it was known to occur.
