Ichthyomyzon Fossor
The northern brook lamprey (''Ichthyomyzon fossor'') is a freshwater fish in the family Petromyzontidae. It is closely related to the silver lamprey (''I. unicuspis'') and may represent an ecotype of a single species with ''I. unicuspis''. Description Northern brook lampreys are jawless fishes, also known as cyclostomes. Northern brook lamprey are considered non-parasitic lamprey. They have poorly developed teeth and a round, disc-like, subterminal mouth, called an oral-disc, for suction. Northern brook lampreys have a single dorsal fin that continues along their entire length until it connects with the caudal fin. This dorsal fin can be notched as well. Their coloration is gray-brown dorsally with a light line down the back and an even lighter ventral side. The length of adult northern brook lampreys does not typically exceed 16 cm and the body is attenuate. While the ammocoetes look similar to the adult lampreys the ammocoetes have a hooded mouth instead of an oral-disc an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ichthyomyzon Gagei
The southern brook lamprey (''Ichthyomyzon gagei'') is a lamprey found in the Southern United States including Arkansas, Louisiana, Mississippi, Alabama, and Georgia. It is a jawless fish with a sucking mouth on one end of it (like a leech). It can appear to be a small eel, since it is rarely longer than one foot in length. Geographic distribution The southern brook lamprey occurs in slow moving rivers and streams from Florida to southern Mississippi, Georgia, and Arkansas along the Gulf Coast west to Oklahoma and Texas.Beamish, F.W.H. 1982. Biology of the Southern Brook Lamprey. Environmental Biology of Fishes. (7) p.305-320. It ranges as far north as Minnesota and Wisconsin, and has been reported to occur in the Chattahoochee river system and the Conecuh River system in Alabama, the Sabine river system in Texas and Louisiana, the Illinois river system in Oklahoma, and the Neches River system in Texas. The southern brook lamprey was thought to be restricted to the southern Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ichthyomyzon Castaneus
The chestnut lamprey (''Ichthyomyzon castaneus'') is a species of lamprey. Description The chestnut lamprey has a maximum length of around , in Canada, with dark grey to olive skin color, blue-black after spawning, and with five to eight bicuspid laterals around its mouth. The chestnut lamprey is closely related to the nonparasitic southern brook lamprey, and the two have been termed a paired species. Distribution and habitat The range of the chestnut lamprey extends from Lake Winnipeg and the Hudson Bay down the Mississippi River to the Central and Eastern United States; this includes any large lakes or reservoirs where large host fish are present. In Canada, the chestnut lamprey has been found in Saskatchewan, Manitoba, Ontario, and Quebec. Ecology Adults are parasitic and feed on larger species of fish to support their body. It was widely presumed that this fish did not feed during the winter, but recent research in Wisconsin has revealed some lampreys remain attached to th ...

Ichthyomyzon Unicuspis
The silver lamprey (''Ichthyomyzon unicuspis'') is a lamprey commonly found in the Northern and Central United States, as well as a large part of southern Canada. Its binomial name means "sucking fish" in Greek and "one-pointed" in Latin. The silver lamprey is a member of the Class Agnatha, sometimes referred to as cyclostomes (round-mouths). Other common names include: Bloodsucker, Blue Lamprey, Hitch-hiker, Lamper, Lamprey Eel. The silver lamprey should not to be confused with the sea lamprey (''Petromyzon marinus''), which has caused considerable damage to native fish populations in the Great Lakes region. Range/Distribution The silver lamprey is commonly found along the Great Lakes and in the Mississippi River and Ohio River and their tributaries from Minnesota to Nebraska, Tennessee, and West Virginia. There have also been a small number of isolated encounters around the Hudson Bay and in the Mississippi River in Mississippi. Identification The silver lamprey is an eel-lik ...

Ichthyomyzon Greeleyi
The mountain brook lamprey or Allegheny brook lamprey (''Ichthyomyzon greeleyi'') is a lamprey found in parts of the Mississippi river basin, New York, Pennsylvania, Ohio, and in the Cumberland River and Tennessee River The Tennessee River is the largest tributary of the Ohio River. It is approximately long and is located in the southeastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names, .... This fish is jawless with a small sucker mouth and a long, eel-like body. It is fairly small, only growing to about in length. The mountain brook lamprey is a non-parasitic lamprey, meaning that they do not attach themselves to larger species of fish. The mountain brook lamprey is believed to have evolved from the parasitic Ohio lamprey (''I. bdellium'') and occurs, often in abundance, within many of the tributaries of the Ohio and Tennessee River systems. All non-parasitic lampreys require two distinctly differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ichthyomyzon Bdellium
The Ohio lamprey (''Ichthyomyzon bdellium'') is a lamprey found in the Ohio River drainage basin in the United States and is a parasitic species of lampreys. They are considered to be an endangered/rare species in some states, due to siltation, pollution, and construction of dams. Description All lampreys have a long, almost eel-like, body with no scales. Lampreys have segments of muscles that are visible along their body called myomeres, and a jawless mouth. In larval lampreys, called ammocoetes, their mouth is not fully developed, very small, and hidden between folds of skin. Adults have a disk shaped mouth with varying amounts of teeth depending on the species. The Ohio lamprey has a single, continuous dorsal fin. Fully grown, Ohio lampreys reach 10-14 inches, but may get to 15 inches. Diet As ammocoetes, Ohio lamprey filter plankton, algae, and other small organic matter. As adults, they attach onto larger prey, such as smallmouth bass, walleyes, redhorse suckers and tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Frédéric Girard
Charles Frédéric Girard (8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Born in Mulhouse, France, he studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil War broke out, he joined the Confederate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
