Swim with whale sharks in Baja, Mexico

MSNBC reports on the adventure of swimming with whale sharks, "the world's largest fish," in the Mexico's Sea of Cortez.

Whale sharks grow up to 40 feet but have very small teeth and aren't predatory. That means they won't try to eat you. Gentle giants, they gather each fall at Bahia de Los Angeles — almost halfway down the Baja Peninsula on the Sea of Cortez — to filter-feed on microscopic organisms called plankton.

The Mexican government also seems concerned about whale sharks, marking off with buoys the part of Bahia de los Angeles where whale sharks congregate and enforcing rules for interacting with the animals. Chasing or herding sharks isn't allowed. No more than three people per boat may be in the water at any time. Touching sharks is prohibited.
