Paddlefish: Anatomy of a Living Fossil

U.S. Army Corps of Engineers, Engineer Research and Development Center

April 13, 2020 | 7:50

The North American Paddlefish, now thought to be the only species of its kind after the presumed extinction of the Chinese Paddlefish, is a living fossil with complex and fascinating anatomical features. ERDC scientists are studying the strong, web-like structure of its rostrum, for example, in hopes of replicating it for use as material to protect military buildings, vehicles and soldiers from attack. Here, ERDC's Jan Jeffrey Hoover provides an in-depth look at Paddlefish anatomy. Paddlefish are native to the Mississippi River and its tributaries. Video produced by Bruce Reid, Lower Mississippi River Conservation Committee, in partnership with ERDC's Fish Ecology Team. To learn more about the LMRCC's work, see https://lmrcc.org.
