Whale sharks are known to pop up once in a while.

This is the whale shark, the largest fish in the world.

That facility has kept at least one whale shark for more than 10 years.

The whale shark is the largest species in this order.

Staff members did not see the same kind of appetite changes in the two female whale sharks, officials said.

A day with whale sharks is unlike anything you will have ever experienced.

At nearly 20 feet long and growing, these two enormous whale sharks are members of the largest fish species on Earth.

Whale sharks are enormous, up to 60 feet long, and peaceful.

Interaction with the whale sharks is regulated by the local department office.
