Sea Turtles in Cancún: Living Treasures of the Mexican Caribbean

Sea Turtles in Cancún: Living Treasures of the Mexican Caribbean

Cancún is much more than white sandy beaches and turquoise waters. Among its most iconic natural treasures are sea turtles, ancient species that have roamed the oceans for over 100 million years. In this coastal paradise of the Mexican Caribbean, a breathtaking natural event takes place each year that captivates tourists, biologists, and nature lovers alike: the nesting and release of sea turtles.

Below, we take a deep dive into the species found in the region, their life cycle, the best places to see them, conservation efforts, and how you can actively help protect them.

Sea Turtle Species in Cancún 

Five of the world’s seven sea turtle species can be found in Mexico, and four of them inhabit the coasts of the Riviera Maya:

1. Loggerhead Turtle (Caretta caretta)
2. Green Turtle (Chelonia mydas)
3. Hawksbill Turtle (Eretmochelys imbricata)
4. Leatherback Turtle (Dermochelys coriacea)

These species are endangered, threatened by coastal urbanization, marine pollution, bycatch in fisheries, and climate change. Their conservation is a national and international priority.

Life Cycle of Sea Turtles

The life cycle of sea turtles is fascinating and filled with challenges from the very beginning. Below are their main life stages:

1. Mating

Mating occurs in the ocean, close to the beaches where females will lay their eggs. In the Riviera Maya, this process typically takes place between April and June. Males never return to land after hatching; only females return to the beaches to nest.

2. Nesting and Egg-Laying

Female turtles return to the same beach where they were born to nest, a phenomenon known as philopatry. The nesting season in the Riviera Maya runs from May to September, with July and August being peak months.

At night, the turtle digs a nest in the sand using her hind flippers and lays between 80 and 120 eggs. She then covers them with sand to protect them from predators and external temperatures.

3. Incubation

Incubation lasts between 45 and 60 days. The sand’s temperature affects the sex of the hatchlings: warmer temperatures usually produce females, while cooler temperatures produce males.

4. Hatching and Release

Once the eggs hatch, the baby turtles emerge together—usually at night—and instinctively head for the sea, guided by the moonlight reflecting on the water.

5. Juvenile and Adult Stage

The hatchlings swim out to sea and spend years in open ocean before returning as adults to the coasts where they were born. Sea turtles reach sexual maturity between 15 and 30 years of age, and can live over 80 years.

Where to See Sea Turtles in the Riviera Maya

The Riviera Maya is one of the best places in the world to observe sea turtles in their natural habitat. Here are some key spots:

1. Akumal

Meaning "place of turtles" in the Mayan language, Akumal is one of the most iconic spots to swim with green and hawksbill turtles in calm, shallow waters.

2. Xcacel-Xcacelito

A protected natural reserve with controlled access. It’s one of the most important turtle nesting sanctuaries in the region.

3. Playa del Carmen and Tulum

The beaches of these destinations also receive hundreds of nests each year. During the season, local organizations allow participation in turtle release activities.

4. Isla Holbox and Isla Mujeres

These islands are also prime locations to see turtles, especially during nesting. In Holbox, you can even spot the leatherback turtle.

Conservation Programs and How to Get Involved

Government and civil organizations work year-round to protect sea turtles in the Riviera Maya. Key activities include:

• Nest monitoring
• Relocation of eggs to protected hatcheries
• Release of hatchlings
• Environmental education in schools and communities
•  

Some well-known organizations are:

• Flora, Fauna y Cultura de México A.C.
• Fundación Ecobahía
• CEA (Centro Ecológico Akumal)
• Quintana Roo Sea Turtle Monitoring Network

As a visitor or local, you can contribute in several ways:

• Participate in organized releases (always under professional supervision)
• Avoid using bright lights or bonfires on the beach at night
• Do not touch turtles or interfere with their journey to the sea
• Reduce single-use plastic consumption
• Support symbolic turtle adoption programs

Current Challenges and Threats

Despite conservation efforts, sea turtles face numerous threats:

• Light pollution: artificial lights disorient hatchlings, causing them to head inland instead of to the sea.
• Plastic pollution: many turtles die from ingesting plastic bags they mistake for jellyfish.
• Illegal trade: despite legal protection, illegal trading of eggs and shells still occurs.
• Climate change: affects incubation temperatures, beach erosion, and ocean currents vital to turtle navigation.

Conclusion: Guardians of the Caribbean

Sea turtles are symbols of resilience, ancient heritage, and natural beauty. Witnessing their life cycle in the Riviera Maya is not only an unforgettable experience but also a call to action: protecting them means preserving the balance of our oceans.

Whether you're a tourist, photographer, biologist, or sea enthusiast, each of us has a role to play. The next time you walk along the beach and see a nesting sign or take part in a release, remember you are witnessing one of the planet’s oldest and most magical events.

Live the experience. Protect the cycle. And let the Riviera Maya teach you to love the ocean from the very root
