The loggerhead sea turtles here in the Caribbean have been tracked to migrate across the Atlantic and back to where there were hatched to breed. It was previously a mystery why there were lengthy gaps in sightings of individual turtles. One individual young turtle released off the coast of Colombia was reported in Haiti 20 -days- later, then later in the Azores, then later off Africa, and years later back in the Caribbean.
