Feel free to call the American paddlefish funny-looking.
“Talk to me when you’ve been around a few more tens of millions of years,” replies the paddlefish, whose ancestors were swimming about North America with the dinosaurs when the earliest humans were still but a distant gleam in Mother Nature’s eye. Cousin to sturgeons, the American paddlefish is another ancient fish, and today it is the last known surviving paddlefish species in the world.
The aptly named paddlefish sports a long, wide, flat snout—technically known as a “rostrum”—that indeed looks like it could be repurposed to power a canoe. It might seem like an ungainly appendage to have sticking off your face, and it does (apologies, paddlefish) lend the fish a somewhat endearingly goofy appearance, like an aquatic Jimmy Durante.
The paddle has a purpose, however. Paddlefish are filter feeders, explains Donald Orth, professor emeritus of fish and wildlife conservation at Virginia Tech; they live off minute zooplankton in the water, like insect and fish larvae and tiny crustaceans. The fish swim with their very large mouths gaping open, straining food from the water through cartilaginous structures known as “gill rakers.” Though this method of feeding gives them the look of a fish either perpetually astonished or yawning, apparently it does the trick.
“When summertime is most productive for zooplankton,” says Orth, “all the paddlefish need to do is open their mouths and swim, and that sieve is very efficient for capturing food.”
So how does the paddle come into play? It is equipped with myriad electroreceptors that detect the weak electrical activity given off by zooplankton in the water column, allowing the paddlefish to more efficiently locate its lunch. This is a particularly handy adaptation since paddlefish apparently don’t have great eyesight and much of the time prefer to inhabit the murky depths of large, slow-moving freshwater rivers, lakes, and reservoirs.
That said, when it’s time to spawn, the fish need a different environment altogether. The American paddlefish’s range today is the Mississippi River basin and its widespread network of tributaries. To reproduce, the fish swim up rivers, seeking shallower water where they lay their eggs on gravel bars swept free of silt by faster-moving spring waters. Paddlefish, thus, are known to be long-distance travelers; in 2025, a paddlefish that had been tagged and released in North Dakota was caught nearly 1,000 miles and several river navigations away in Kentucky. This migratory habit is how the fish come to Virginia, in fact. They can be found seasonally in the Clinch and Powell rivers in the southwest region of the state, likely swimming up from the vast Norris Reservoir in Tennessee.
And speaking of reservoirs, that the fish’s lifecycle depends on this periodic migration is one reason why the paddlefish has run into trouble. Dams have obstructed the fish’s movement and, in some cases, cut off populations from access to spawning grounds altogether.
Then there is the unfortunate fact (for the paddlefish) that the fish is good eating. “It is as good as some of the best freshwater fish, and it has no bones,” explains Orth. “This is a cartilaginous skeleton. It means that you can easily get quite a bit of flesh out of a single fish.” That alone might not have spelled trouble for the paddlefish, but paddlefish roe, it turns out, makes for an excellent caviar. “Most of us would not be able to tell the difference between sturgeon and paddlefish caviar,” Orth says.
As access to traditional sturgeon caviar plummeted, demand for paddlefish caviar rose, leading to overfishing (and an increasing problem with illegal poaching where fishing restrictions have been put in place).
On the positive side, researchers have learned how to successfully hatch, raise, and release juvenile paddlefish to help restock and restore populations. Video from the Missouri Department of Conservation shows the process, which in four months produces a squirming soup of juvenile paddlefish 6–10 inches long and each already sporting a miniature rostrum. “They are as cute as you can imagine,” says Orth.
Not that they’ll stay that way. Paddlefish have a potential lifespan of 50 years or more, and for a fish that lives off the ittiest bits in the aquatic food chain, they can pack it on impressively, reaching lengths of as much as 7 feet and weighing up to 150 pounds or more; a world-record 164-pounder was caught in Lake of the Ozarks in 2024. That heft puts them among North America’s largest freshwater fish, along with the white sturgeon, alligator gar, and lake sturgeon—all also fellow members of the big-and-ancient club.
But if there were a winner for sheer whimsy? Surely the paddlefish would have it by a nose.
