They dragged the shark from the waves to the beach, trapping its head in a rubber ring while laughing as it starts floundering and suffocates.
Apparently, the video was filmed in the Dominican Republic, with lifeguards from Hard Rock Hotel & Casino in Punta Cana.

We can only hope that people will start to finally value animals lives, more than their pursuit for a perfect selfie.
