About the Trip


Sea turtles are one of the main groups that CREMA  (Centro de Rescate de Especies Marinas Amenazadas) works with.


During our sea turtle expedition dives, we will proceed to directly catch turtles during dive activities or catch them by means of special turtle nets.  Only the biologists are allowed to catch turtles, but we always need assistance bringing the turtle on-board and during other procedures.

Turtles are brought on board for weighing and measuring.  We obtain tissue samples for genetic and stable isotope analysis, and proceed to tag with external metal flipper tags.

Measuring Sea Turtle in Costa Rica


The Bats Islands (Murcielago Archipelago) belong to the National Park of Santa Rosa, that include a protected marine area with a great diversity of marine life. The scenery is spectacular and you can appreciate both the beauty of the sea and of the archipelago.

Worldwide, the islands are considered one of the best bull shark dive sites. This dive site is for Advanced Certified Divers only as conditions regarding depth and strong swells can be demanding.


The Bats are most famous for the chances of seeing the Bull sharks. There is no feeding and encounters are completely natural.

During this expedition we will visit the Catalina Islands (weather permitted), an archipelago of over 20 Islands and rocky outcrops. This area is famous for diving with Oceanic Mantas from December - March.


The area is currently unprotected, and is heavily used by the dive tourism industry, the sports fishing industry, and the small-scale fisheries industry.


We are working with local conservation groups for a protection status to be granted to the site.

Manta at Catalinas Islands


We will visit a sea turtle nesting beach. This time of the year is the season for critically endangered leatherback turtles and endangered green turtles.


Although our main priority is to see nesting leatherback turtles, it may not be possible. Numbers of nesting leatherbacks at Las Baulas National Park has declined 98% during the last two decades.

Depending on nesting activity and the advice provided by the Park Rangers, we may change the objective and seek for nesting green turtles in Playa Nombre de Jesús, a nearby nesting beach. We will as well assist, local volunteers in their work to preserve the nesting areas.

Sea Turtles Mating in Costa Rica


As part of this expedition we included two Ecology Specialty Certifications: Sea Turtle and Shark Ecology.


In the Shark Ecology program, you will learn how to interpret shark behaviours, why they are often misunderstood and how to dive with sharks. This is a perfect course for shark fans and for divers who are nervous about sharks but want to overcome their fear.


The Turtle Ecology program provides the skills and concepts you need to recognize and identify common sea turtle species. It teaches you about the fascinating history of sea turtles, their role in marine ecosystems and threats to their survival.


Both courses are digital learning online and upon completion  you will earn your Specialty certifications.
