Continuing on the shark theme since I just finished reading a ton on great whites again.
Did you know that if a person is missing at sea, they are “missing, presumed drowned”? In order for it to be attributed to sharks, there has to be direct proof that a shark was involved.
Here’s a classic case (cited from Great White Shark):
A girl and her boyfriend went kayaking by themselves. She turns up dead a few days later with a shark bite that looks like a great white shark took a big chunk out of her. Their kayaks are found later, lashed together with a hole in the bottom of hers that matches the bite taken out of her. His kayak is just empty.
She died from a great white shark. He is missing presumed drowned.
