It is a shark eats shark world at the COEX Aquarium located in South Korea.
A female sand tiger shark has been filmed with a male bounded hound shark in its mouth.
The attack happened at around 6:30pm yesterday and 21 hours later only the smaller sharks tail was visible.
Aquarium staff believes the seven foot female may have been protecting her ‘turf’.
Oh Tae-youp,PR manager of COEX aquarium told Daily Mail “Sharks have their own territory. However, sometimes when they bump against each other, they bite out of astonishment.”
The article added that aquarium staff expect the shark will not be able to digest the smaller 4ft shark and will end up regurgitating the remains in about a week.
