In the clip, which was recorded by WPTV news anchor Ashleigh Williams and posted to Facebook, a man in swim trunks wrestled around with the shark in the tide before dragging it by the tail into the sand.
He used both hands to hold the squirming shark down as onlookers took photos while he posed for over 30 seconds.
Eventually, another man – previously seen holding a fishing pole – dragged the fish back out into the surf. Williams noted that the shark was returned deeper into the waves after the video ended, and said "it did not resurface for several minutes."
Commenters were quick to chide the man, with one Facebook user writing, "I feel this is cruel. I am sure it was brought into our world by the guy with the fishing pole, they should have released it immediately.. My opinion..."
Another poster added, "Leave the shark in the water where it belongs! This is an example of inconsiderate human behavior! I would not have sympathy if the shark bit him!"
Others took the opposite stance, noting the legality of fishing for blacktips.
According to WPTV, the Florida Fish and Wildlife Conservation Commission said that the man's actions were completely legal, as fishing for sharks from the shore is allowed in state.
Added Florida Atlantic University biological science professor Dr. Stephen Kajiura, "This is what some people do for their hobby. They have fun with that."
He went on to explain, however, that the fish's thrashing could have lead to fatal internal injuries – things fishermen might often miss.
Both unidentified fisherman from the video told Williams that the shark was returned to the water in less than 90 seconds.
Would You High-Five a Great White Shark?!
The incident comes shortly after a group of tourists accidentally killed an endangered dolphin while taking numerous selfies with the creature.
Last year, another dolphin in China and a shark in New York both died on beaches while humans kept them out of the water for photo opportunities.
