Facts
The American Paddlefish was first seen in the sixteenth century
by Europeans when Hernando De Soto explored the Mississippi
River. The American Paddlefish has sometimes been called a
spoonbill, spoonbill cat, or shovelnose cat because some people
have mistaken the American Paddlefish as being a member of the
Catfish family. It is interesting that the young
Paddlefish have teeth, but the adults do not have teeth, yet
they both still feed on the same prey. Paddlefish are the
oldest surviving animal species in North America at 300 million
years! The actual size of the smallest known American
Paddlefish is 11/16 of an inch long. The North American
record for the largest Paddlefish weighed 144 pounds from Dam
No. 7 in Kansas caught in 2004. The other only remaining
member of the Polyodontidae Family is the Chinese Paddlefish,
Psephurus gladius, is in even more risk of extinction
on the other side of the world in the Yangtze River.

People should find the
American Paddlefish interesting for many reasons. One
reason is the American Paddlefish's paddle-like rostrum; its
rostrum is unique compared to the typical fish that comes to
mind when people envision a fish. This organism does not
have any scales on its body except for a little on its tail.
Another reason why people would find this particular fish
species interesting is because it is a primitive fish that lived
more than 300 million years ago, a time even before the
dinosaurs! A third reason why other people might find the
American Paddlefish interesting is because it is a species that
is
at risk of being extinct.
