Paddlefish

Paddlefish, any of various freshwater relatives of the sturgeon, resembling a shark with a long, paddlelike snout. A Mississippi River paddlefish, also known as the spoonbill sturgeon, grows to 6 ft (1.8 m) in length, and another, the swordbill sturgeon of the Yangtze River in China, may grow to twice that size. Paddlefish are sometimes eaten, and their large black eggs make caviar.
