Green turtle links Costa Rica’s Cocos Island with Ecuador’s Galapagos

To this day, scientists have tracked three different turtles that have traveled between two of the most fragile and important island ecosystems: The Galapagos Islands in Ecuador and The Cocos Island in Costa Rica. We are just starting to understand the importance of these breeding grounds and their interconnectivity with turtle migration and reproduction.

One normal migration for turtles, one giant discovery for humankind.

With his 14-day journey from the waters of Costa Rica’s Cocos Island National Park to the Galapagos Marine Reserve in Ecuador, “Sanjay,” an endangered green sea turtle, established the first direct migration link between the two protected areas.

Sanjay was one of three green sea turtles tagged by scientists from the marine conservation groups Turtle Island Restoration Network and PRETOMA during a 10-day research expedition. Using a $4,000 satellite tag, biologists from the organizations were able to map Sanjay’s exact migration.

“It’s truly remarkable. Sanjay knew where he was headed, and made a beeline from one marine protected area to the next,” said Alex Hearn, conservation science director for Turtle Island Restoration Network. “These protected areas of ocean are hot spots for endangered green sea turtles, but we also need to think about their migratory corridors between protected areas.”

    • Salut Laurent. En fait, la menace est moins de se retrouver dans la soupe en plus le problème d’être “prises accessoires” des grands navires de pêche. De toute façon, it is a shame. Il doit y avoir un moyen de fournir la vie marine avec un passage sûr entre les zones protégées.
