Pearl Dace
''Margariscus'', known as the pearl daces, is a genus of leusiscid fishes found in North America. There are currently two recognized species in this genus. Margariscus comes from the Greek word ''margariskos,'' meaning pearl.

Theodore Dru Alison Cockerell
Theodore Dru Alison Cockerell (1866–1948) was an American zoology, zoologist, born at Norwood, England, and brother of Sydney Cockerell. He was educated at the Middlesex Hospital Medical School, and then studied botany in the field in Colorado in 1887–90. Subsequently, he became a taxonomist and published numerous papers on the Hymenoptera, Hemiptera, Mollusca and plants, as well as publications on paleontology and evolution. Personal life Cockerell was born in Norwood, Greater London and died in San Diego, California. He married Annie Sarah Fenn in 1891 (she died in 1893) and Wilmatte Porter Cockerell, Wilmatte Porter in 1900. In 1901, he named the ultramarine blue chromodorid ''Mexichromis porterae'' (now ''Felimare porterae'') in her honor. After their marriage in 1900, they frequently went on collecting expeditions together and assembled a large private library of natural history films, which they showed to schoolchildren and public audiences to promote the cause of en ...

Leuciscidae
Leuciscinae is a subfamily of the freshwater fish family Cyprinidae, which contains the true minnows. Members of the Old World (OW) clade of minnows within this subfamily are known as European minnows. As the name suggests, most members of the OW clade are found in Eurasia, aside from the golden shiner (''Notemigonus crysoleucas''), which is found in eastern North America. According to ancestral area reconstruction, the subfamily Leuiciscinae is thought to have originated in Europe before becoming widely distributed in parts of Europe, Asia and North America. Evidence for the dispersal of this subfamily can be marked by biogeographical scenarios/observations, geomorphological changes, phylogenetic relationships as well as evidence for vicariance events taking place through time. Through analyses and evidence of divergence time, it was observed that the two monophyletic groups, the phoxinins and the leuciscins, had shared a common ancestor dating to approximately 70.7 million year ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Margariscus Margarita
The Allegheny pearl dace (''Margariscus margarita'') is a species of cyprinid fish. It is demersal, freshwater fish, with a dark green back and silvery body. This species is omnivorous, consuming algae, as well as arthropods. ''M. margarita'''s range spans southern Canada and the northern United States. While not considered endangered at the federal level in the United States, several states either consider this species endangered or threatened; it faces threats of habitat destruction and invasive species. Description ''M. margarita'' is a bottom-dwelling freshwater fish that has been recorded to reach sizes of , however, it does not commonly grow beyond about . The maximum age ''M. margarita'' has been recorded to reach is four years. The body is long with small eyes and mouth. There are eight rays each in the dorsal fin, anal fin, and pelvic fins. The dorsal side is dark green in colour, with silvery flanks and a grey or white ventral side. Between late autumn and summer, males ...

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Margariscus Nachtriebi
The northern pearl dace (''Margariscus nachtriebi'') is a freshwater ray-finned fish Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or h ... in the family Cyprinidae, the carps and minnows. It occurs in Atlantic, Hudson Bay, Great Lakes, and Mississippi River basins in the northern United States and Canada. Its preferred habitat is cool, clear headwater streams, bog drainage streams, ponds and small lakes, and in stained, peaty waters of beaver ponds, usually over sand or gravel.
