March 24 (UPI) -- A Florida man walking over a bridge took video when he came across an unusual sight: an alligator and a bull shark swimming side by side in a river.
Gray Vinson said he was walking on a bridge over the Indian River Lagoon in Vero Beach when he spotted the bull shark and alligator swimming in tandem just a few feet apart.
"It's not everyday you see a bull shark and a gator swimming together in the Indian River," Vinson wrote on Facebook.
Vinson said bull sharks are known to use the Indian River Lagoon as nursery rounds, but the alligator was a surprising sight, especially so close to its fellow predator.
"I was shocked to see the alligator," Vinson told CBS Miami. "I was looking to see if any of the bull sharks were there since they normally are this time of year."
