Frequently Asked Questions (FAQs)

What is the average number of eggs laid in a sea turtle nest?

The average number of eggs laid in a sea turtle nest varies by species, but typically ranges from 80 to 120 eggs. Loggerhead turtles often lay larger clutches than green sea turtles. The incubation period also varies, usually lasting around 50 to 60 days.

How long does it take for sea turtle hatchlings to reach the ocean?

Hatchlings typically emerge from their nests at night and instinctively crawl towards the brightest horizon, which is usually the ocean. This journey can take anywhere from a few minutes to several hours, depending on the distance to the water. It’s crucial to ensure there are no artificial lights confusing them, as light pollution can lead them astray.

What is the survival rate of sea turtle hatchlings?

The survival rate of sea turtle hatchlings is extremely low. It’s estimated that only one in 1,000 hatchlings survives to adulthood. They face numerous threats, including predation by birds, crabs, and fish, as well as challenges finding food and avoiding entanglement in marine debris.

How can I identify different sea turtle species while observing nesting activities?

Identifying sea turtle species requires careful observation of their physical characteristics. Loggerheads have reddish-brown shells and large heads; green sea turtles have smooth, heart-shaped carapaces; and hawksbills have hooked beaks and serrated shell edges. Consulting field guides and seeking advice from local experts can also be helpful.

Are there guided tours available to observe sea turtle nesting in Cancun?

Yes, several eco-tourism companies in Cancun offer guided tours to observe sea turtle nesting.
