Whaleshark scuba dive in Placencia, Belize

Whale sharks are the largest fish in the world. They can grow up to 40 feet long and over 20 tons.

But they are hardly sea monsters.

Whale sharks are said to be gentle and curious and sometimes pull up alongside fishing boats. They don't seem to mind snorkelers who visit their underwater hunts.

So where might you catch sight of a whale shark?

Well, they typically swim in warm tropical waters that are rich with plankton.

One such spot is right along the coast of Belize, in Central America and we are looking for the name of a Belizian town that is famous for whale sharks.

The resort town is about a two hour drive from Belize's capital, Belmopan.

Anchor Aaron Schachter talks to Ann Marie Macneil, who guides snorkelers on whale shark excursions, about the experience of coming face to face with a whale shark.
