It’s not a whale and it’s not a shark, actually – but the world's largest fish. Swim with these gentle mammoths that can be 59 feet long and weigh 15 tons. Rest assured that whale sharks eat only plankton and small fish, so as a human you’re safe!
What to Expect
Spend 2 hours swimming with whale sharks in the Sea of Cortez on a great and safe adventure. While whale sharks have thousands of teeth in hundreds of rows in their enormous mouths, they can neither bite nor chew. They’re happy to forego all human body parts in favor of plankton, krill, and small fish.
The whale shark got its name because it’s the only fish that is literally as big as a whale. Mature adults can reach almost 60 feet in length and weigh nearly 20 tons.
Reaching these proportions requires an immense amount of energy, which the whale shark gets by consuming huge volumes of plankton-rich water, then straining it out through its gills. In fact, to get the food it needs it’s not unusual for a whale shark to filter 400,000 gallons of water per hour!
To conserve this hard-won energy and continue eating, whale sharks tend to do a lot of hanging about in the water, or, if moving, doing so at a very slow pace. This makes it possible for humans to jump in and swim alongside them for a bit.
Of course, when they want to put on the speed they certainly can, so when a whale shark tires of your company, all you’ll see is a swishing tail receding into the distance.
