Least Brook Lamprey
The least brook lamprey (''Lampetra aepyptera'') is a common, non-parasitic lamprey Lampreys (sometimes inaccurately called lamprey eels) are an ancient extant lineage of jawless fish of the order Petromyzontiformes , placed in the superclass Cyclostomata. The adult lamprey may be characterized by a toothed, funnel-like s ... distributed in the Mississippi River watershed, and a limited range along the Atlantic coast. Description As with all lamprey species, the least brook lamprey spends the majority of its life as a worm-like ammocoete. The ammocoete (5 mm–20 cm) is clear with a pigmented head when small (<5 cm), but becomes a dark/golden brown as it matures. Ammocoetes have pigmented eye spots located in the head that can detect light and dark. After metamorphosis from the ammocoete into the juvenile stage, the lamprey becomes a golden color with yellow-tinged fins. Teeth (often used to identify lamprey to species) develop on the oral disk, and the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Conrad Abbott
Charles Conrad Abbott (June 4, 1843 – July 27, 1919) was an American archaeologist and naturalist. Biography Abbott was born at Trenton, New Jersey, son of Timothy and Susan (Conrad) Abbott; grandson of Joseph and Anne (Rickey) Abbott, and a descendant of John and Anne (Mauleverer) Abbott, settlers, from England, in New Jersey in 1684. He studied medicine at the University of Pennsylvania School of Medicine. During the American Civil War, he served as a surgeon in the Union Army. He received his M.D. degree from University of Pennsylvania in 1865, but never entered into the practice of the profession. In 1876, he announced the discovery, later confirmed by other archaeologists, of traces of human presence in the Delaware River Valley dating from the first or "Kansan" ice age, and inferentially from the pre-glacial period when humans are believed to have entered upon the North American continent. However, today the consensus of archaeologists is that most of Abbott's "Trenton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is the largest and most extensively accessed online database on adult finfish on the web.Marine Fellow: Rainer Froese ''Pew Environment Group''. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications.

Lamprey
Lampreys (sometimes inaccurately called lamprey eels) are an ancient extant lineage of jawless fish of the order Petromyzontiformes , placed in the superclass Cyclostomata. The adult lamprey may be characterized by a toothed, funnel-like sucking mouth. The common name "lamprey" is probably derived from Latin , which may mean "stone licker" ( "to lick" + "stone"), though the etymology is uncertain. ''Lamprey'' is sometimes seen for the plural form. There are about 38 known extant species of lampreys and five known extinct species. Parasitic carnivorous species are the most well-known, and feed by boring into the flesh of other fish to suck their blood; but only 18 species of lampreys engage in this micropredatory lifestyle. Of the 18 carnivorous species, nine migrate from saltwater to freshwater to breed (some of them also have freshwater populations), and nine live exclusively in freshwater. All non-carnivorous forms are freshwater species. Adults of the non-carnivorous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freshwater Fish Of The Southeastern United States
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 wate ...

Endemic Fauna Of The United States
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1860
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, 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 vertebrate, 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 placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
