Diving with Green Turtles (Tortuga verde – Chelonia mydas) in the azure waters of Costa Rica is an adventure that immerses you in the wonders of marine life.
The Green Turtle, distinguished by its olive-green shell and herbivorous diet, graces the coastal and underwater landscapes of Costa Rica with its presence.
Diving with Green Turtles in Costa Rica provides a unique opportunity to connect with nature, emphasizing the importance of sustainable tourism and conservation efforts to ensure the preservation of these magnificent creatures and the breathtaking underwater world they inhabit.
Feeding Behavior
Green turtles are herbivorous marine reptiles known for their diet primarily consisting of seagrasses and algae. They have specialized jaws adapted for tearing and grinding plant material.
These turtles maintain the health of seagrass beds in shallow coastal areas by grazing on them, making them essential for the ecosystem. They also eat algae from rocks and coral.
Reproduction and Life Cycle
Green turtles have a unique reproductive cycle that involves migration. They typically return to the same beaches where they were born to nest. The females come ashore to lay their eggs in nests they dig in the sand.
After laying eggs, the females return to the sea, leaving the eggs to incubate on their own.
The incubation period lasts around two months, after which the hatchlings emerge and make their way to the ocean. This is a perilous journey as they face predation from various animals.
Once in the ocean, the young turtles spend several years floating in open water, often in oceanic currents, where they continue to grow and feed. They eventually return to coastal areas as subadults and adults to continue their herbivorous diet and complete their life cycle.
Threats
Green turtles face several threats to their survival:
Habitat Destruction:Coastal development, especially the destruction of nesting beaches and seagrass beds, poses a significant threat to green turtles.
Illegal Poaching: The collection of green turtle eggs and hunting of adults for their meat and shells are major problems in some regions, despite legal protections.
Fishing Bycatch: Green turtles often become unintentional bycatch in fishing nets and longlines, leading to injuries and death.
Climate Change: Rising temperatures can skew the gender ratio of hatchlings, as warmer nests tend to produce more females. Additionally, climate change can affect the availability of seagrass, a key food source.
Pollution: Green turtles can ingest plastic pollution in the oceans, leading to health issues related to ingestion.
When to See Them
The timing for seeing green turtles varies depending on the region:
Nesting Season: To witness adult green turtles nesting, you should visit their nesting beaches during the nesting season, which typically occurs in the summer months in many tropical regions. The exact timing can vary by location.
Hatchling Emergence: To observe hatchlings emerging from their nests and making their way to the sea, you should be present during the hatchling season, which typically follows the nesting season by a couple of months.
Subadults and Adults: To see subadult and adult green turtles feeding in coastal areas, you can visit these regions year-round. Coastal areas with seagrass beds and suitable feeding grounds are where you are most likely to encounter them.
Remember that green turtles are a protected species in many countries, and it’s essential to observe them responsibly and in accordance with local regulations to minimize disturbances and ensure their conservation.
Lora Turtle (Olive Ridley Turtle) – Lepidochelys olivacea in Costa Rica

Diving with Lora Turtles in Costa Rica is not just an adventure; it’s a profound encounter with one of nature’s most captivating marine species, leaving you with unforgettable memories of the wonders beneath the waves.
Feeding Behavior
Olive Ridley turtles primarily feed on a variety of marine invertebrates like crabs, shrimp, and jellyfish, exhibiting opportunistic feeding behavior. They scavenge for food, consuming whatever prey is readily available in their coastal and oceanic habitats.
Reproduction and Life Cycle
The Olive Ridley turtle’s nesting behavior is famous for its arribada, a synchronized mass nesting event where thousands of females come ashore to lay their eggs on the same beach during a short period. After selecting a suitable nesting site, they dig a nest cavity and deposit their eggs. Unlike some other sea turtle species, Olive Ridleys do not exhibit maternal care and leave the eggs to incubate on their own.
The incubation period lasts around 45-55 days, after which the hatchlings emerge and make their way to the ocean. This journey is fraught with danger as they are vulnerable to predators, such as birds and crabs. Olive Ridley turtles spend several years as pelagic (open-ocean) juveniles before returning to coastal areas as subadults and adults.
Threats Lora Turtle
Olive Ridley turtles face various threats to their survival:
Habitat Destruction: Coastal development, pollution, and the destruction of nesting beaches are significant threats to their nesting sites.
Bycatch: These turtles are often unintentionally caught in fishing nets and longlines, leading to injuries and mortality.
Egg Harvesting: Illegal collection of Olive Ridley turtle eggs for consumption is a problem in some regions, despite legal protections.
Marine Debris: Ingestion of plastic and marine debris can harm these turtles, both directly and indirectly.
Climate Change: Rising temperatures can influence the sex ratio of hatchlings, as warmer nests tend to produce more females.
When to See Them in Costa Rica
In Costa Rica, you can witness the spectacular arribadas of Olive Ridley turtles during their nesting season. The timing can vary slightly from year to year, but it typically occurs from July to December, with peak arribadas often taking place between August and October.
These mass nesting events are a breathtaking natural phenomenon that draws visitors from around the world. They want to witness the turtles’ nesting rituals.

Tortuga Carey (Hawksbill Turtle) – Eretmochelys imbricata in Costa Rica
Tortuga Carey, also known as the Hawksbill Turtle (Eretmochelys imbricata), holds a special place in the rich biodiversity of Costa Rica.
These magnificent sea creatures are vital to the marine ecosystem, playing a crucial role in maintaining the health of coral reefs by controlling sponge populations.
Recognizable by their distinctive, overlapping shell plates and pointed beak, Hawksbill Turtles are listed as critically endangered, making conservation efforts in Costa Rica imperative.
The country’s coastline, including nesting sites in places like Tortuguero National Park, provides crucial habitats for these turtles.
Costa Rica has been working diligently to protect these ancient mariners, implementing strict conservation measures, patrolling nesting areas, and raising awareness among locals and tourists alike about the importance of preserving these magnificent creatures for future generations.
Feeding Behavior
Hawksbill turtles primarily feed on sponges, but their diet also includes other invertebrates such as jellyfish and sea anemones. Their narrow, pointed beaks are adapted for reaching into crevices on coral reefs, allowing them to extract their preferred prey.
This specialized feeding behavior helps maintain the health of coral reef ecosystems.
Reproduction and Life Cycle
Hawksbill turtles, like other sea turtle species, return to the beaches where they were born to lay their eggs. After nesting, the females leave the eggs to hatch on their own. The hatchlings make their way to the sea and spend several years floating in oceanic currents. Feeding on various small organisms.
Upon reaching a certain size, juvenile hawksbill turtles settle in shallow coastal areas. Including coral reefs, where they continue to feed and grow. They reach xexual maturity at around 20-30 years of age. And hawksbill turtles then participate in the annual breeding migrations and nesting.
