The American paddlefish, Polyodon spathula, also called the Mississippi paddlefish or spoonbill, is a paddlefish living in slow-flowing waters of the Mississippi River drainage system. It appears to have been extirpated from Lake Erie and its tributaries. They are closely related to the sturgeons. This large Chondrostean freshwater fish may grow to 220 cm (7 feet) and weigh up to 100 kg (220 pounds). The paddlefish takes its common and scientific names from its distinctive snout, which is greatly elongated and flattened into a paddle shape. The American paddlefish is believed to use sensitive electroreceptors on its paddle to detect prey, as well as to navigate while migrating to spawning sites. The American paddlefish feeds primarily on zooplankton but also feeds on crustaceans and bivalves. Polyodon spathula is one of two living species of Paddlefish; the other is the possibly extinct Chinese Paddlefish, Psephurus gladius.

Famous quotes containing the word american:
“The white American man makes the white American woman maybe not superfluous but just a little kind of decoration. Not really important to turning around the wheels of the state. Well the black American woman has never been able to feel that way. No black American man at any time in our history in the United States has been able to feel that he didn’t need that black woman right against him, shoulder to shoulder—in that cotton field, on the auction block, in the ghetto, wherever.”
—Maya Angelou (b. 1928)
