Footage shared to social media shows the bloodied victim climbing onto a fishing charter boat, having been ferried over from a smaller boat, off the coast of Miami, Florida.

A picture and video of the incident was shared to the Hot Shot Charters Instagram page on Monday, with the caption: “Hot Shot saves diver after being attacked by shark.”

A second post revealed the rescue happened at Key Biscayne, which is an island town in Miami-Dade County, Florida.

The video shows the bitten man on his back with his left arm elevated, still bleeding despite being wrapped in a tourniquet that appeared to be fashioned from a T-shirt.

With blood soaking the diver’s blue wetsuit and a huge gash on his left arm, the injured man gives the charter crew the thumbs up with his other hand.

On his back, the diver communicates with charter crew by speaking in Spanish.

An ambulance rushed a 40-year-old man from Key Biscayne to Jackson Memorial Hospital's Ryder Trauma Center on Saturday morning, according to local news reports.
