Green turtles were first tagged with flipper tags at Tortuguero, Costa Rica in 1955. Since then, almost 48,000 sea turtles have been tagged at Tortuguero. Some of these turtles have been recaptured by fishermen and others away from the Tortuguero nesting beach, providing us with useful information about sea turtle migrations and emphasizing the shared nature of the sea turtle resource.
Today, sea turtles are tagged at many projects throughout the Caribbean. Collaboration between conservation organizations in Costa Rica is demonstrated by the leatherback tag return map that includes information from four tagging projects. Although flipper tagging has helped us to learn much about sea turtle migration, satellite telemetry has to be employed to find out the exact movements of sea turtles after they leave the nesting beach.
