Footage shows the shark ended up in shallow water before the man spotted it and dragged it on to the beach
The video was taken just days after a baby dolphin died in Buenos Aires, Argentina, while beach-goers passed it around in order to take selfies with it.
The Franciscan dolphin, listed as 'vulnerable to extinction', was plucked out of the ocean by gawpers before people began taking pictures.
While the dolphin is a mammal, and so will not struggle to breathe in air, it does have a very thick layer of fatty tissue to keep it warm underwater, and so being exposed to the harsh South American sun likely caused it to dehydrate and overheat.
Last year saw a record number of shark attacks worldwide, with people bitten 98 times, smashing the previous record of 88, set in 2000.
Of the 59 that took place in the United States, around half took place in Florida with the rest spread across North and South Carolina, Hawaii and California.
In a highly unusual attack, a man was also bitten while boogie boarding off Long Island in New York, in a sight that sharks are being drawn further up the coast by warmer sea waters.
Tens of thousands of the predators are currently migrating through the warm waters around Florida and are swimming very close to shore according to researchers
While the exact species of shark feature in the video is unknown, most of the migrating sharks are thought to be blackfins
