The American paddlefish is a species of ray-finned fish. It is the only living species of paddlefish (Polyodontidae). This family is most closely related to the sturgeons; together they make up the order Acipenseriformes, which are one of the most primitive living groups of ray-finned fish. Fossil records of other paddlefish species date back 125 million years to the Early Cretaceous, with records of Polyodon extending back 65 million years to the early Paleocene. The American paddlefish is a smooth-skinned freshwater fish with an almost entirely cartilaginous skeleton and a paddle-shaped rostrum (snout), which extends nearly one-third its body length. It has been referred to as a freshwater shark because of its heterocercal tail or caudal fin resembling that of sharks, though it is not closely related. The American paddlefish is a highly derived fish because it has evolved specialised adaptations such as filter feeding. Its rostrum and cranium are covered with tens of thousands of sensory receptors for locating swarms of zooplankton, its primary food source. The only other species of paddlefish that survived to modern times was the Chinese paddlefish, last sighted in 2003 in the Yangtze River in China and considered to have gone extinct no later than 2010.
The Honey War was a bloodless territorial dispute in 1839 between Iowa Territory and Missouri over their border.
The Lamine River is a 63.8-mile-long (102.7 km) tributary of the Missouri River in central Missouri in the United States. It is formed in northern Morgan County, about 4 miles (6 km) southeast of Otterville by the confluence of Flat and Richland creeks, and flows generally northwardly through Cooper and Pettis counties. In northwestern Cooper County the Lamine collects the Blackwater River and flows into the Missouri River northeast of Lamine and 6 miles (10 km) west of Boonville. At Clifton City, the river has a mean annual discharge of 455 cubic feet per second. Below the mouth of the Blackwater River, its discharge averages 1,279 cubic feet per second
The Crooked River is a tributary of the Missouri River in west-central Missouri in the United States. The stream has also been known historically as "Big Creek," "Little River" and "Tiger River." The Crooked River was named for its meandering disposition. Big Creek refers to the stream's status as the largest tributary to the Missouri River in the county.
The mountain sucker is a sucker found throughout western North America, on both sides of the Rocky Mountains, including the upper Missouri River, Columbia River, Sacramento River, and Colorado River. It is not limited to higher altitudes but is known from locations as high as 2,800 m (9,200 ft). It is a slender, streamlined fish typically under 20 cm (8 in) in length. It is generally olive green or brown above, with pale underparts, and breeding males have a lateral red-orange band and fins suffused with the same color. It is mainly herbivorous, feeding on algae and diatoms. Breeding takes place in late spring and early summer in gravelly riffles in small streams.
The shovelnose sturgeon is the smallest species of freshwater sturgeon native to North America. It is often called "hackleback", "sand sturgeon", or "switchtail". Switchtail refers to the long filament found on the upper lobe of the caudal fin. Shovelnose sturgeon are the most abundant sturgeon, found in the Missouri River and Mississippi River systems, and the only commercially fished sturgeon in the United States of America.
The Rio Grande silvery minnow or Rio Grande minnow is a small herbivorous North American fish. It is one of the seven North American members of the genus Hybognathus, in the cyprinid family.
Hybognathus is a genus of ray-finned fish in the family Cyprinidae. Its members are collectively known as the silvery minnows. Hybognathus are pelagophils that are native to North America. The populations of such pelagophils, including species of Hybognathus, continue to decrease in their natural habitats.
The sicklefin chub is a species of ray-finned minnow fish in the family Cyprinidae. It is found only in the United States. It is one of the 324 fish species found in Tennessee, and is a species of concern in the Charles M. Russell National Wildlife Refuge in Montana.
The common shiner is a freshwater fish of the family Cyprinidae, found in North America. It ranges in length between 4 and 6 inches, although they can reach lengths of up to 8 inches.
The Ozark minnow is a species of ray-finned fish in the genus Notropis.
The brassy minnow is a species of fish belonging to the family Cyprinidae. The family Cyprinidae consists of mainly freshwater minnows and carps. The fish gets its scientific name from the Greek word Hybognathus, meaning bulging jaw, and hankinsoni from the American scientist, T.L. Hankinson. It is commonly found throughout the northern United States and Canada.
The Cypress minnow is a species of freshwater ray-finned fish from the carp family Cyprinidae. It is endemic to the United States where it occurs in the Mississippi and Ohio drainages as well as some other rivers which drain into the Gulf of Mexico.
The Mississippi silvery minnow is a species of fish in the family Cyprinidae. It is one of the 324 fish species found in Tennessee. Relative to other minnows, the Mississippi Silvery Minnow is a large minnow. These minnows require a body of water with little to no current. The most documentation of these minnows is from the Little and Great Miami river along with the Ohio river and tributes off these rivers. In terms of conservation, the population in Ohio is at an all-time low, but overall there is little conservation concern about this specific minnow. In general there has been little research done on the Mississippi silvery minnow.
The plains minnow is one of the 324 fish species found in central United States. It is a large minnow that was once a common bait fish. The plains minnow requires shallow, slow-moving streams to complete its life cycle. Pollution, dams, and introduced sport fish have caused populations to decline.
Bigeye chub is a species of freshwater fish in the carp family (Cyprinidae).
The eastern silvery minnow is a freshwater fish. They are characterized by their lack of barbels. In appearance, they are similar to shiners, but the lower jaw is crescent-shaped rather than U-shaped and there is a secondary loop in the gut, which is sometimes visible through the body wall of preserved specimen.
Cambarus hubrichti is a species of decapoda in the family Cambaridae. The species goes by the common name Salem cave crayfish.
