Whale Shark, Mexico

Recently, we asked our Facebook fans to tell us about their favorite vacation spots. For Betsy Snider, it's "Isla Mujeres, Mexico, to swim with whale sharks."

The island, near Cancun, is a popular place for wildlife-watchers. The commingling of the Caribbean Sea and the Gulf of Mexico creates a plankton-rich environment. Hundreds of the sharks gather each summer to filter feed on the tiny organisms. There's nothing tiny about whale sharks, however—they are the largest fish in the sea. Here, a feeding shark with huge mouth agape dwarfs a diver.
