America. Closely related to the sturgeon, it is one of only two extant
taxa in the paddlefish family (the other being the Chinese paddlefish).
Fossil records of paddlefish date back over 300 million years ago,
nearly 50 million years before dinosaurs appeared. The American
paddlefish is referred to as a relict species (because it retains some
morphological characteristics of its early ancestors) even though it is
highly derived with evolutionary adaptations specifically for filter
feeding. The rostrum and cranium of American paddlefish are covered with
tens of thousands of sensory receptors for locating swarms of
zooplankton, their primary food source. American paddlefish are native
to the Mississippi River Basin and once moved freely under the
relatively natural, unaltered conditions that existed prior to the early
1900s. Their numbers have declined dramatically primarily because of
overfishing, habitat destruction, and pollution. They are currently
found in only twenty-two U.S. states, and their range has been reduced
to the Mississippi and Missouri river tributaries and Mobile Bay
drainage basin.
