On Thursday, at the COEX Aquarium in Seoul, South Korea, a female shark ate a male shark over a turf war. The eight-year-old female sand tiger shark bit and then fully consumed the five-year-old male banded houndshark. Amateur shark enthusiasts might assume that the male owed her money or mouthed-off. It turns out she's just a bad ass.

Oh Tae-youp, an aquarium official, said that he likely bumped into her, and she assumed it was an act of aggression over turf:

Sharks have their own territory. However, sometimes when they bump against each other, they bite out of astonishment. I think the shark swallowed the whole body, because they usually eat it all when they bite the head part.
