In what was likely a turf war at a Seoul aquarium, a female sand tiger shark has eaten a male banded hound shark. 

It took the 8-year-old female 21 hours to eat the 5-year-old male inside a tank at the COEX Aquarium. According to video of the consumption, the female shark started with the male's head and slowly went about consuming the rest of his body. 

This act of shark cannibalism likely was the result of the sharks bumping into one another. "Sharks have their own territories," an aquarium official told Reuters. "Sometimes, when they bump into each other, they bite out of astonishment."

Despite her best efforts to make a meal of the male shark, the female shark is expected to at some point regurgitate the remains of her former roommate.
