4 Star 88x31Turtle Island leads primary research with volunteer dive research assistants at Cocos Island National Park, Costa Rica, an oasis of ocean life. Hundreds of sharks and rays, schools of fish numbering in the tens of thousands and endangered sea turtles surround the island.  Our research is setting the basis for better protections at Cocos Island and for a “Protected Swimway” to save sharks, sea turtles and other migratory animals as they swim throughout the region.
