How did Pirates star Tamayo Perry die of shark attack? What we know so far

Pirates of the Caribbean star and a professional surfer Tamayo Perry died after he was attacked by a shark while surfing off the island of Oahu in Hawaii on Sunday afternoon, authorities said. City and County of Honolulu Ocean Safety lifeguard Tamayo Perry, 49, died in the attack near Goat Island, Shayne Enright of the Honolulu Emergency Services Department said in a statement.
Honolulu Ocean Safety and the city's fire, police and emergency medical services departments responded to Mālaekahana Beach on Oahu's North Shore just before 1 pm after a caller reported seeing a man who appeared to have suffered shark bites, Enright said.
Perry took a break from his lifeguard duties and went surfing near Goat Island near Laie. Lifeguards brought Perry to shore by jet ski and paramedics assisted with the death pronouncement.

Perry was the victim of multiple bites though it's not yet clear whether there was one shark or several behind the attack
The provocation behind the shark attack is yet to be ascertained. Sharks generally can attack a human mistaking it as prey.
Who is Tamayo Perry?
Perry, who worked as a lifeguard on the North Shore, began his career with the Ocean Safety department in July 2016, Enright said.
Ocean Safety personnel posted shark warnings in the area following the attack, Enright said. Honolulu Ocean Safety Acting Chief Kurt Lager said Perry was “a lifeguard loved by all.”
“He's well known on the North Shore. He's a professional surfer known worldwide,” Lager said at a news conference. “Tamayo's personality was infectious and as much as people loved him, he loved everyone else more.” “Tamayo was a legendary waterman and highly respected,” Honolulu Mayor Rick Blangiardi said, calling Perry’s death “a tragic loss.”
