Swim & Snorkel with These Gentle Giants, Which Are Actually the World's Largest Fish!
Just off the tip of Mexico’s Yucatan Peninsula is a small island largely untouched by tourism. Isla Holbox might go unnoticed entirely, except for some highly noticeable visitors that frequent its warm ocean waters each summer. Their presence is hard to ignore, since they average 40 feet long and weigh 15 tons. These are gentle whale sharks—not whales at all, despite their size, but actually the world’s largest fish. Docile and unafraid, they allow us
to swim close enough to observe the checkerboard pattern of pale yellow dots and stripes covering their thick gray skin. If you're looking for a fish tale to trump all others, this is it!
