A Leatherback Sea Turtle Migrates 12,774 miles

In the longest "ever recorded migration of any sea vertebrate, a leatherback sea turtle recently completed a 12.774 miles across the Pacific Ocean. The journey, tracked by satellite, provides the first record of a trans-Pacific migration by a leatherback.

The giant reptile began the trek in Indonesia's warm tropical waters in the summer of 2003.

Along the way, the turtle may have encountered swordfish, tuna, and other migrating leatherbacks returning after a successful foraging season off the North American coast.

Some of the turtle's dives sent it plunging into the cold darkness 3,300 feet (1,000 meters) below the ocean surface.

After 647 days of swimming, the animal finally reached the cool waters of the Pacific Northwest—where a feast of jellyfish awaited.

The turtle made this "epic journey spanning tropical and temperate waters of the Pacific just to eat jellyfish off Oregon," said Scott Benson of NOAA's Southwest Fisheries Science Center in Moss Landing, California.

Those must be some really good jellyfish!!!!
