VIDEO: Watch a giant fish swallow a shark whole

Well, this is horrifying.

You kind of presume sharks are at the top of the food chain, don't you?

Well, this video will make you rethink everything you thought you knew about what goes on in the ocean.

These guys were out fishing when they hooked a shark. Granted it wasn't a huge one but it was fairly big - around four feet. Then out of nowhere, a massive grouper - a type of fish - comes up from the deep and SWALLOWS THE SHARK WHOLE.

Great, another thing to add to the list of what to be afraid of.
