Marine Life
There are two distinct snorkeling opportunities off Isla Mujeres that attract divers and underwater photographers year after year. These are swimming with sailfish from mid-December to mid-March and swimming with whale sharks during the summer. All year round you can spot some turtles, rays, a variety of tropical Caribbean fish, moray eels, reef sharks, and many more.
What To See In Isla Mujeres
Snorkeling With Whale Sharks
Isla Mujeres is a great place for whale shark tours. Whale sharks gather during the summer in two areas. Most operators will snorkel off Isla Holbox, where the whale sharks gather to feed on plankton and krill. Other operators will take snorkelers way off Isla Mujeres to clear blue water, where whale sharks and mantas feed on bonito eggs after spawning events. Depending on the day, there can be many whale sharks or not so many whale sharks, but the chances of seeing them are generally high.
Snorkeling With Sailfish
Those who wish to dive with sailfish will spend up to 8 or 10 hours on a boat searching for the sailfish as they hunt and control schools of baitfish. Sea conditions can be rough, and like any natural encounter, the sailfish are not guaranteed to show up. The encounters with sailfish will be brief as it is one of the fastest fish in the sea, but it is an incredible experience.
Scuba Diving the Sleeping Sharks Cave
Away from other dive spots lies a mysterious cave where different species of sharks like to sleep. Because of this, the dive site is called the Sleeping Sharks Cave. The high oxygen content in water bubbles is what makes it a perfect sleeping spot for sharks. This is also a great way for scuba divers to closely observe the sharks. The majority of the sharks are nurse sharks but you can also see the gray reef, blacktip sharks and even bull sharks have been spotted sleeping there. Besides the sharks, turtles, jacks, and rays can be also seen.
Scuba Diving Musa, the Underwater Museum
Isla Mujeres does not only offer some great marine life encounters, but it is also home to a spectacular underwater museum. Museode Arte Subacutico or shortly called MUSA, is a contemporary museum that has over 500 life-sized sculptures for display. There are a variety of interesting sculptures like a Volkswagen Beetle that are surrounded by playful fish. The museum can be visited both by scuba diving or snorkeling.
