Green sea turtles (Chelonia mydas) are Cozumel’s serene grazers, with smooth olive-green shells and gentle, paddle-like flippers that glide effortlessly through seagrass beds. You’ll spot them munching on the lush underwater lawns from June through September when they come ashore to nest, then spend the rest of the year cruising coastal waters in search of their favorite salad bar. These herbivores can travel up to 2,000 miles between feeding and nesting sites yet always return to familiar beaches—so keep your eyes peeled during our “Blue Pearl” trips for a peaceful green turtle encounter. Their placid nature and striking, mossy hues make every sighting a soothing, unforgettable moment beneath the waves.

Loggerhead sea turtles (Caretta caretta) are the ocean’s gentle giants, easily recognized by their broad, heart-shaped shells and powerful jaws. These curious creatures nest on Cozumel’s sandy beaches from April through July, then return to the warm Caribbean waters to forage along vibrant reefs. Though they travel thousands of miles between feeding and nesting grounds, loggerheads always seem to find their way back home—making every sighting around the “Blue Pearl” boat trip a true highlight of your dive adventure.

Sea Turtle Facts and Information
Peak Sightings
- Nesting Season on Shore: May through September, especially June–July nights on quieter eastern beaches.
- Foraging Season on Reefs: Year-round, but most often seen on dives from May to October, when sponges are abundant.
How to Spot Them
- Beak & Shell Shape: Look for their signature narrow, hooked “hawk-like” beak and overlapping scutes that give the carapace a serrated outline.
- Habitat: Glide slowly around coral overhangs and ledges—hawksbills love picking sponges from crevices at 10–30 meters depth.
- Behavior: They tend to cruise close to the reef rather than open water. Watch for sudden pauses as they nibble on sponges.
Fun Facts
- “Tortoiseshell” Treasure: Their beautifully patterned shell once fueled a massive jewelry trade—today it’s protected under CITES Appendix I.
- Longevity & Maturity: They can live 30–50 years, but don’t reach breeding age until around 20–30 years old.
- Multiple Nests: A single female may lay 3–5 clutches per season, each with ~100 eggs—yet only about 1 in 1,000 hatchlings survives to adulthood.
- Spongivores of the Reef: Hawksbills help maintain coral health by eating sponges that would otherwise outcompete corals.
Other Important Information
- Conservation Status: Critically endangered—threats include bycatch, coastal development, plastic pollution, and illegal poaching.
- Local Protection Efforts: Cozumel Dive Center partners with beach-patrol programs to monitor nests, relocate vulnerable clutches, and rear hatchlings through their most dangerous early days.
- Responsible Diving Tips:
- Don’t touch or chase turtles—let them approach if they’re curious.
- Avoid fin kicks near fragile corals.
- Choose eco-certified operators who use mooring buoys, not anchors.
- Don’t touch or chase turtles—let them approach if they’re curious.
- Why They Matter: As natural reef gardeners, hawksbills control sponge overgrowth, promoting coral diversity and resilience—essential for Cozumel’s vibrant dive sites.

Peak Sightings of Sea Turtles
- Nesting Season on Shore: June through September, with the highest activity in July–August on the island’s quieter beaches.
- Foraging Season on Reefs: Year-round, but especially abundant June–October when seagrass beds are lush.
How to Spot Them
- Shell & Flippers: Look for their smooth, heart-shaped carapace with olive-green to brown tones and large paddle-like flippers.
- Habitat: You’ll find them grazing in shallow seagrass meadows (2–10 m depth) off the western coast, and resting under bommies or near reef ledges.
- Behavior: Often seen slow-swimming or bobbing at the surface to breathe—follow the gentle rise and fall of their heads.
Fun Facts
- Strict Herbivores: Adults eat primarily seagrass and algae, helping keep meadows healthy and productive.
- Long Migrations: Some Cozumel greens travel over 1,500 miles between nesting sites in Central America and feeding grounds around the Yucatán.
- Slow to Mature: They can live 60+ years but don’t reach sexual maturity until around 25–35 years old.
- Cold-Blooded Navigators: They use Earth’s magnetic fields to navigate back to their natal beaches.
Other Important Information
- Conservation Status: Endangered—threats include boat strikes, entanglement in fishing gear, coastal development, and marine debris.
- Local Protection Efforts: Cozumel Dive Center supports beach-patrol and hatchling-release programs; nests are monitored nightly and relocated if at risk.
- Responsible Diving & Snorkeling Tips:
- Keep a respectful distance—never chase or corner them.
- Swim slowly to avoid startling them or stirring up sediment.
- Support operators who use seagrass-friendly anchoring (mooring buoys).
- Keep a respectful distance—never chase or corner them.
- Ecosystem Role: By grazing seagrass, green turtles promote new growth, which stabilizes the sea floor, supports crustaceans and fish nurseries, and helps sequester carbon.

Peak Sightings of Sea Turtles
- Nesting Season on Shore: April through July, with most nests laid in May–June on Cozumel’s quieter eastern beaches.
- Foraging Season on Reefs: Year-round, but especially common May–September when ocean currents bring an abundance of invertebrate prey.
How to Spot Them
- Head & Shell: Look for their broad, blocky head and powerful jaws—ideal for crushing shells—and a reddish-brown, heart-shaped carapace about 2½–3 feet long.
- Habitat: Often found cruising along reef drop-offs at 15–40 m depth, or resting under overhangs in deeper channels; occasionally seen in more open water.
- Behavior: Slow, deliberate swimmers. Watch for their distinctive rolling motion as they use large front flippers to “fly” through the water.
Fun Facts
- Conch Crushers: Their strong jaws let them eat hard-shelled prey like conchs, sea urchins, and whelks—key predators in reef ecosystems.
- Long-Distance Travelers: While Cozumel’s loggerheads may nest here, some individuals migrate over 3,000 km between feeding and nesting sites.
- Size & Longevity: Adults can weigh 170–400 lb and live for 50 + years, yet don’t reach sexual maturity until around 30 years of age.
- Ancient Mariners: Loggerheads have swum the world’s oceans for over 100 million years, making them one of the oldest surviving turtle species.
Other Important Information
- Conservation Status: Vulnerable—threats include bycatch in fishing gear, coastal development, marine debris ingestion, and nighttime beachfront lighting.
- Local Protection Efforts: Cozumel Dive Center works with sea-turtle organizations to patrol nesting beaches at night, record and relocate at-risk nests, and release hatchlings safely at dawn.
- Responsible Diving Tips:
- Maintain a respectful distance—never touch or chase turtles.
- Avoid fin kicks that could damage fragile reef structures.
- Choose dive operators using mooring buoys rather than anchors.
- Maintain a respectful distance—never touch or chase turtles.
- Ecosystem Role: By preying on hard-shelled invertebrates, loggerheads help keep reef communities balanced, which supports coral health and overall biodiversity.
