A blacktip shark roamed near unsuspecting swimmers in the waters off South Beach in Miami Beach, Florida.

In the video, two swimmers are seen at the top of the screen, while the filmer captures a blacktip shark passing nearby beneath them.

"The lifeguard told me they were blacktip sharks, which migrate along this coast at this time of year," the filmer told Newsflare.

The footage was shot on March 17, 2018.
