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.
All he did was accidentally bump into her. It then took her 21 hours to slowly swallow and consume him until just the tip of his tail was visible. While this is technically due to the shark's digestive system, it was also a warning to other clumsy males to remind them what happens if you bump into her or give her a weird look.
