Visitors at a South Korean aquarium watched in amazement at a shark swimming in a tank with another shark¡¯s tail hanging out of its mouth.

While sharks do not tend to eat others of the same specieswhen they are in captivity and they have regular feeds, experts at the aquarium said that sharks have their own territory, and when they occasionally bump against each other, they bite out of astonishment.

The smaller shark which fell prey to its bigger counterpart was a banded hound shark. The bigger beast was a sand tiger shark.
