With a size that most often averages 12 meters length (40 feet), whale sharks are the biggest fish in the sea. Even though they are listed as Vulnerable to extinction in the IUCN Red List of Threatened Species, you can see them congregating in large amounts in various areas of North and Central America. It is possible to snorkel with them, following the code of conduct you’ll be introduced to on the boat.

Often called “gentle giants”, whale sharks are filter feeders. They are attracted by waters abundant in zooplankton, and other small organisms such as releases of eggs from fish or coral spawning. While they usually are solitary, you may see hundreds at a time coming to feed in certain areas and seasons.

If you have a camera, contribute to whale sharks identification and conservation by taking pictures of the area above their left pectoral fin. Upload them to the Wild Book for Whale Sharks. This database uses NASA’s star algorithm to identify and track whale sharks.

Holbox & Isla Mujeres, Mexico

Whale sharks are frequently seen North of Holbox and Isla Mujeres between June and September. They are coming to feed on the fish eggs of the little tuny. Up to 420 whale sharks have been counted in the “Afuera” area. This annual event also draws thousands of tourists every year, and the Mexican government created some regulation to follow when snorkeling with the gentle giants. They ask snorkelers to remain at least 5 meters away (16 feet) from the whale sharks, and the boats, 10 meters (32 feet). To see all regulations, consult holboxguide. The trip costs around USD $110 per person.

La Paz, on the Sea of Cortez in Mexico is a hot spot for biodiversity, attracting whale sharks between January to April.

At this time of the year in La Paz, the water temperature drops, and it can get as low as 20 degrees celsius (68 Farenheit). Some shops can organize a tour all the way from Cabo San Lucas. Keep in the driving part (about two hours one way) and expect to pay around USD $200 per person for the day trip.

Gladden Spit, South Belize, is an area on the reef about 50 km (40 miles) of Placencia. It takes one and a half hour by boat to reach, and whale sharks are going there to feed in the spawning events of many different tropical fish. April and May are the best months to see whale sharks. Local dive shops recommend going just before the full moon, and up to 10 days after. The day trip in Belize usually costs about USD $200 per person. You may see some whale sharks in Gladden Spit, but don’t expect to see as many as in Holbox or Bahia de los Angeles in Mexico. These are some of the few places in the world to attract such a concentration of whale sharks seasonally.
