Mostly bullsharks were the culprits.
Got their teeth into it....
No I believe they were oceanic whitetips.
FWIW, after I caught a white tip off Maui, I did a little research:
Famed oceanographic researcher Jacques Cousteau described the oceanic whitetip as “the most dangerous of all sharks”. Despite the greater notoriety of the great white shark and other sharks habitually found nearer the shore, the oceanic whitetip is responsible for more fatal attacks on humans than all other species combined, as a result of predation on survivors of shipwrecks or downed aircraft. Such incidents are not included in common shark-attack indices for the 20th and 21st centuries, and as a result of this, the oceanic whitetip does not have the highest number of recorded incidents. Nonetheless, incidents involving the oceanic whitetip total in the thousands worldwide, with one incident alone, the torpedoing of USS Indianapolis on 30 July 1945, alleged to have accounting for 600 to 800 sailors, though the most reportedly died from exposure to the elements rather than from shark attacks.
