Female tiger shark eats her male tankmate
(CNN) -- Forget the TV version of "Shark Tank." This is what life is like in a REAL shark tank: A female sand tiger shark wasn't messing around when she made a fish meal of her tankmate. It was a startling sight for visitors at Coex Aquarium in Seoul, South Korea, as the 8-year-old shark slowly consumed a 5-year-old male shark.
