Oceanic whitetips, which most of those are, do indeed consume humans. Many argue that they are the most prolific killers of all. They are fund in the middle of nowhere in the ocean. If you wind up in a life raft or in a shipwreck, those are what is coming for you.
I’ve heard that about oceanic white tips too. The middle of the ocean is pretty barren of resources, so they can’t take the chance of passing up any potential meal.
