1 – Summertime is the prime time for whale sharks. From mid-May to mid-September on Mexico’s Caribbean coast, whale sharks are out on their summer vacations. Some 1,400 travel from Africa, Central America and even Australia to these warm, planktonrich waters.
2 – You don't have to be a diver; Snorkelers are welcome, too. Pick an eco-friendly licensed operator with an experienced captain and crew. Ceviche Tours in Isla Mujeres and EcoColors in Cancun are our top picks.
3 – Don't touch the whale sharks. Not because you'll lose a finger, but because they're endangered. All eco-tour companies believe in the preservation of these docile creatures and seek to keep the human footprint (or flipper kick, rather) to a minimum.
4 – These herculean fish rarely swim alone. Smaller fish species, such as pilot fish, swim in close proximity to whale sharks, most likely for protection. Enemies of these smaller fish are probably intimidated by the whale shark's size and therefore steer clear.
5 – Each fish has its own pattern of spots and stripes. No two are alike, and you can help track them. At the Whale Shark Festival in Isla Mujeres (generally mid-July), join Project Domino by adding your underwater photos to the database. You may see your new friend again next year.
