Luxilus Zonatus
The bleeding shiner (''Luxilus zonatus'') is a freshwater ray-finned minnow in the family '' Leuciscidae'', which was recently changed to distinguish between North American and Asian minnows. It occurs in tributaries of Ozark-draining tributaries of the Missouri, and Mississippi rivers in southern Missouri and northeastern Arkansas. Its preferred habitat is rocky and sandy pools and runs of headwaters, creeks and small rivers. Taxonomy Class: Actinopterygii, Order: Cypriniformes, Family: ''Leuciscidae'', Genus: ''Luxilus'', Species: ''L. zonatus''. The bleeding shiner was originally known to be classified as the ''Alburnus zonatus'' by Agassiz in 1863. Formerly known to be in the genus ''Notropis'', but removed and added to the genus ''Luxilus'' in 1989. Originally the now distinct species of ''L. zonatus'' and ''N. Pilsbryi'' were considered to be synonymous, but after carefully observing the morphological evidence they were added to the ''Luxilus'' genus. Description ...

Frederic Ward Putnam
Frederic Ward Putnam (April 16, 1839 – August 14, 1915) was an American anthropologist and biologist. Biography Putnam was born and raised in Salem, Massachusetts, the son of Ebenezer (1797–1876) and Elizabeth (Appleton) Putnam. After leaving college, Ebenezer had for a short time engaged in fitting young men for college, but soon went into business in Cincinnati as a commission merchant, a line in which he was successful. Recalled to Salem by his father's death in 1826, Ebenezer married there and devoted himself to the study and cultivation of plants and fruits, and involved himself in the Democratic Party in his county. Although frequently offered office, Ebenezer never accepted, except to serve as alderman in the so-called “model-government” of Salem when that town was first chartered as a city, and as postmaster of Salem.''The Cyclopædia of American Biography'', 1918 Frederic's early studies were at private schools, and with his father at home. He became curator of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meramec River
The Meramec River (), sometimes spelled Maramec River, is one of the longest free-flowing waterways in the U.S. state of Missouri, draining Blanc, Caldwell, and Hawk. "Location" while wandering Blanc, Caldwell, and Hawk. "Executive Summary" from headwaters southeast of Salem to where it empties into the Mississippi River near St. Louis at Arnold and Oakville. The Meramec watershed covers six Missouri Ozark Highland counties—Dent, Phelps, Crawford, Franklin, Jefferson, and St. Louis—and portions of eight others— Maries, Gasconade, Iron, Washington, Reynolds, St. Francois, Ste. Genevieve, and Texas. Between its source and its mouth, it falls . Year-round navigability begins above Maramec Spring, just south of St. James. The Meramec's size increases at the confluence of the Dry Fork, and its navigability continues until the river enters the Mississippi at Arnold, Missouri. History The name likely means 'the river of ugly fishes' or 'ugly water' in Algonquian. Earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1863
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and 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 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 external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods ...

Freshwater Fish Of The 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 wa ...

Clear Creek (Illinois)
Clear Creek is a southern Illinois watercourse that rises in Jackson County and Union County, and discharges into the Mississippi River in Alexander County. Upper and lower halves Clear Creek is neatly divided by the bluffs of the Mississippi into two sections: nearer its headwaters it is a relatively clean and swift-flowing hill river, and in its lower half, below the bluff, it has become a channelized ditch, the ''Clear Creek Ditch'' (coordinates: ). Clear Creek rises in the uplands of the Shawnee Hills near Cobden, Illinois. In its upper reaches, Clear Creek is an unusually clean and undisturbed stream for Illinois, as its watershed includes two of the largest wilderness areas in Illinois, Bald Knob Wilderness and Clear Springs Wilderness. Another section of the creek's watershed is protected by the Trail of Tears State Forest, and most of the remainder of the watershed is protected by the non-wilderness parcels of Shawnee National Forest. West of Jonesboro, Illinois, C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spawn (biology)
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and marine reptile, reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing Ovum, ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mos ...

Bleeding Shiner Distribution Map
Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery. Types * Upper head ** Intracranial hemorrhage – bleeding in the skull. ** Cerebral hemorrhage – a type of intracranial hemorrhage, bleeding within the brain tissue itself. ** Intracerebral hemorrhage – bleeding in the brain caused by the ...

Demersal Fish
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone).Walrond Carl . "Coastal fish - Fish of the open sea floor"Te Ara - the Encyclopedia of New Zealand. Updated 2 March 2009 They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters they are found on or near the continental shelf, and in deep waters they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word ''demersal'' comes from the Latin ''demergere'', which means ''to sink''. Demersal fish are bottom feeders. They can be contrasted with pelagic fish which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four percent), whereas pelagic fish can contain up to 30 percent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...
