Phenacobius
''Phenacobius'', the suckermouth minnows, is a genus of cyprinid fishes endemic to the United States. Historically the suckermouth minnow was not found as far eastward as Ohio, now they seem to be a stable species living throughout the Midwest and parts of southern states such as Texas, New Mexico, and Alabama. Many forests and prairies were cleared out to make farmland, this caused for drainage streams and rivers to take form, moving the minnows eastward. Originally the suckermouth minnows probably never crossed the Mississippi River prior to the developed farm land. They have a lifespan of roughly 3–5 years, but is hard to measure due to predation, survival rate of about 50 percent. There are currently five described species. Etymologically, "phenacobius" means "deceptive life", possibly because these species eat insects despite an herbivorous appearance. Species * '' Phenacobius catostomus'' D. S.

Phenacobius Crassilabrum
The fatlips minnow (''Phenacobius crassilabrum'') is a species of suckermouth minnow that was first described in the upper Tennessee River system. No fewer than 20 specimens were used for description, and the epithet ''crassilabrum'' (from the Latin ''crassus'' meaning thick or fat and labrum, or lip) was assigned to the species, separating it from '' Phenacobius catostomus,'' with which it had previously been identified. The first holotype specimen collected in 1947 was an adult female in length from the River. Geographic distribution The distribution of the fatlips minnow is restricted to North America, where it occurs in the upper Tennessee River drainage in western Virginia, western North Carolina, eastern Tennessee and northeastern Georgia. Its habitat is gravel and riffles in small to medium creeks. The fatlips minnow is believed to have arisen from a ''P. catostomus'' -like stock population that re-invaded the upper Tennessee River via reciprocal stream piracy. A genetic ...

Phenacobius Mirabilis
''Phenacobius mirabilis'', or the suckermouth minnow, is a North American cyprinid fish, where it occurs in the Mississippi River basin from Ohio and West Virginia to Wyoming, Colorado and New Mexico, and from southeastern Minnesota to northern Alabama and southern Oklahoma. It also occurs in the western Lake Erie drainage in Ohio Ohio () is a state in the Midwestern region of the United States. Of the fifty U.S. states, it is the 34th-largest by area, and with a population of nearly 11.8 million, is the seventh-most populous and tenth-most densely populated. The sta .... Ecology The suckermouth minnow inhabits small to moderate size streams with clear to turbid water. They prefer a water temperature of 5-25 degrees Celsius and a mixed sandy gravel substrate. Streams with permanent flow and riffles with little siltation are ideal for this species. A highly adaptable species, it has been observed that these minnows can travel long distances.

Minnow
Minnow is the common name for a number of species of small freshwater fish, belonging to several genera of the families Cyprinidae and Leuciscidae. They are also known in Ireland as pinkeens. Smaller fish in the subfamily Leusciscidae are considered by anglers to be "true" minnows. Types of minnows Bluntnose minnow (''Pimephales notatus''): The bluntnose minnow is a primary bait fish for Northern America, and has a very high tolerance for variable water qualities, which helps its distribution throughout many regions. The snout of the bluntnose minnow overhangs the mouth, giving it the bluntnose. There is a dark lateral line which stretches from the opercle to the base of the tail, where a large black spot is located. The average size of the adult is approximately 5 cm (2 in). 'Pimephales'' Common shiner (''Notropis cornutus)'': These fish are one of the most common type of bait fish and are almost exclusively stream dwellers. The common shiner can be identified b ...

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 ...

Piscivore
A piscivore () is a carnivorous animal that eats primarily fish. The name ''piscivore'' is derived . Piscivore is equivalent to the Greek-derived word ichthyophage, both of which mean "fish eater". Fish were the diet of early tetrapod evolution (via water-bound amphibians during the Devonian period); insectivory came next; then in time, the more terrestrially adapted reptiles and synapsids evolved herbivory. Almost all predatory fishes (most sharks, tuna, billfishes, pikes etc.) are obligated piscivores. Some non-piscine aquatic animals, such as whales, sea lion and crocodilians, are not completely piscivorous, often also preying on invertebrates, marine mammals, waterbirds and even wading land animals in addition to fish; while others, such as the bulldog bat and gharial, are strictly dependent on fish for food. Some creatures, including cnidarians, octopuses, squid, spiders, cetaceans, grizzly bears, jaguars, wolves, snakes, turtles and sea gulls, may have fish as signific ...

Carnivores
A carnivore , or meat-eater (Latin, ''caro'', genitive ''carnis'', meaning meat or "flesh" and ''vorare'' meaning "to devour"), is an animal or plant whose food and energy requirements derive from animal tissues (mainly muscle, fat and other soft tissues) whether through hunting or scavenging. Nomenclature Mammal order The technical term for mammals in the order Carnivora is ''carnivoran'', and they are so-named because most member species in the group have a carnivorous diet, but the similarity of the name of the order and the name of the diet causes confusion. Many but not all carnivorans are meat eaters; a few, such as the large and small cats (felidae) are ''obligate'' carnivores (see below). Other classes of carnivore are highly variable. The Ursids, for example: While the Arctic polar bear eats meat almost exclusively (more than 90% of its diet is meat), almost all other bear species are omnivorous, and one species, the giant panda, is nearly exclusively herbivorous. ...

Iteroparous
Semelparity and iteroparity are two contrasting reproductive strategies available to living organisms. A species is considered semelparous if it is characterized by a single reproductive episode before death, and iteroparous if it is characterized by multiple reproductive cycles over the course of its lifetime. Iteroparity can be further divided into continuous iteroparity (primates including humans and chimpanzees) and seasonal iteroparity (birds, dogs, etc.) Some botanists use the parallel terms monocarpy and polycarpy. (See also plietesials.) In truly semelparous species, death after reproduction is part of an overall strategy that includes putting all available resources into maximizing reproduction, at the expense of future life (see § Trade-offs). In any iteroparous population there will be some individuals who die between their first and second reproductive episodes, but unless this is part of a syndrome of programmed death after reproduction, this would not be called ...

Promiscuous
Promiscuity is the practice of engaging in sexual activity frequently with different Sexual partner, partners or being indiscriminate in the choice of sexual partners. The term can carry a moral judgment. A common example of behavior viewed as promiscuous by many cultures is the one-night stand, and its frequency is used by researchers as a marker for promiscuity. What sexual behavior is considered promiscuous varies between cultures, as does the prevalence of promiscuity. Different standards are often applied to different genders and civil statutes. Feminism, Feminists have traditionally argued a significant double standard exists between how men and women are judged for promiscuity. Historically, stereotypes of the promiscuous woman have tended to be pejorative, such as "the slut" or "the harlot", while male stereotypes have been more varied, some expressing approval, such as "the stud" or "the player", while others imply societal deviance, such as "the womanizer" or "the philand ...
