The ocean is terrifying.

University of Delaware researchers caught a dogfish shark that grabbed hold of the itty bitty menhaden fish used as bait. A rather ho hum affair until a sand tiger shark appeared out of nowhere.

We caught one large female on our first line Friday, but we were not expecting to catch her like this! This unlucky smooth dogfish couldn't resist the menhaden used as bait and unfortunately fell victim to one of the top predators in the bay. The dogfish was about 3 feet long and completely swallowed by the sand tiger shark.
