Despite their name, whale sharks are part of the shark family: Rhincodontidae, so they are more sharks than whales. They are cold blooded, not mammals. They only resemble whales in size and in feeding. Whale sharks have wide mouths with small baleen teeth they use to filter plankton. That’s why they can be seen close to the surface of the warmest tropical waters in the world: from Honduras to the Maldives.

Both diving and snorkeling are acceptable, but snorkeling may have some advantages over diving. Not just because it allows non-divers to get close to these marvelous creatures. Whale sharks in Mexico are usually swimming in shallow waters, so dive equipment is not required. Snorkelers, just wearing fins and masks move faster and easier than divers, due to the lack of heavy dive tanks and equipment.
