Shark swallows shark in Seoul aquarium - VIDEO
Size and power won the day, and by the time the aquarium opened Friday, only the tail of the smaller shark was visible -- poking from the jaws of its larger female tank mate.
"The sand tiger shark`s instincts are to attack if its territory is threatened, especially during breeding periods," a spokesman for the aquarium said.
The shark appeared to have swallowed its victim whole, and the spokesman said it would probably regurgitate the hound shark after failing to digest it.
"But that could take up to a week," he added.
