cookie cutter sharks usually eat by biting chunks out of larger sea creatures and swimming away, they're also known to eat squid.
a swimmer was swimming across a channel in hawaii when the lights on the boats of his team attracted squid and the cookie cutter shark(s).
below are graphic images of the bites.
