Drone Captures The Largest Swarm Of Sea Turtles Ever Filmed

Yet, in November 2016, biologist Vanessa : managed to film probably the largest swarm of sea turtles to date, while flying her drone over the Costa Rican coastline. The drone was used in a study that investigated olive ridley sea turtles and their reproduction.

The footage, shown in the video above, depicts thousands of olive ridley sea turtles swimming across an area just off Ostional National Wildlife Refuge. It's estimated that there is roughly one turtle for every square meter in the footage. The congregation is so dense that you could almost imagine hopping over the sea by leaping from shell to shell. In fact, the number of turtles in the video might only be the tip of the iceberg. You can visibly see new turtles rising from the depths as the drone ascends, so there might be many more turtles hidden from view below the surface.
