The “Good Juju Group”. An amazing and resilient group, welcomed by leatherback hatchlings and gifted with a very special full-moon night alongside four nesting mama leatherbacks (close to half a ton, 6 feet in length each one of them). 🐢🌕💚 Lots of games, laughter, and fun cultural activities—all in the middle of the jungle! 🌿.

MATING: WHERE THE NEXT GENERATION BEGINS 🐢🌊
Long before a female sea turtle crawls ashore to nest, reproduction begins at sea.
During mating, males use their long, curved claws on the front flippers to hold onto the female. But what happens afterward is even more fascinating: females can store viable s***m, allowing them to fertilize multiple clutches throughout a nesting season.
And there may be more than one father. Multiple paternity occurs in sea turtles, meaning hatchlings within the same clutch can sometimes have different fathers. Its frequency varies among species and populations.
One encounter beneath the surface can therefore contribute to multiple nests and hundreds of eggs. 🐢🌊

MILLIONS OF YEARS OF EVOLUTION 🐢
The evolutionary history of turtles stretches back more than 200 million years, but much of the diversity we see among living turtles today arose within the last ~50 million years.
For sea turtles like the green turtle (Chelonia mydas, ~35 million years ago), life in the ocean came with remarkable adaptations. Unlike many other turtles, sea turtles cannot retract their heads into their shells. Their tough, keratinized head scales help protect this exposed part of their body while maintaining a streamlined form for life at sea.

Millions of years of evolution, written in their scales. 🌊🐢.

Olive my Ridleys 🫒🐢 Group! What a way to experience sea turtles! 🌊. Witnessed a one-day arribada, celebrated the release of more than 40 green sea turtle hatchlings on their final day, and worked hands-on with 33 nesting Olive Ridley sea turtles. 🐢💚.

From nesting mothers to tiny hatchlings making their way toward the ocean, it was an unforgettable few days of fieldwork, conservation, and learning along one of Costa Rica’s most extraordinary coastlines. 🇨🇷🌊

Some nights you go looking for sea turtles… and the universe puts on a show. 🌌🐢!
Night patrols, like-minded students, shooting stars, tropical beaches, expert field researchers, night-walks and sea turtle conservation — just another night in the field with BIOMA.

As we are about to end the summer and Unis start again for the Fall Quarter! We want to start sharing our amazing summer 2026 Groups and stories!
The “Torthemian Rapsotuga” Group 😂! 🎶. Great energy to take on hot, sweaty days, meteors lighting up our nights, and increasing sea turtle nesting activity as the days went by! 🌊🐢☄️.
And to top it all off, an amazing karaoke night that had everyone singing, laughing, and having a blast! 🎤🎶
Pura Vida team and good luck back at Uni!
