Harold (Loggerhead) is 319 km SW off the coast of Portugal and 1543 km from Funchal


Harold is a loggerhead sea turtle that was rescued as a straggler hatchling from a nest on Bogue Banks, North Carolina. Volunteers with the North Carolina Sea Turtle Project rescued the hatchling and took it to the North Carolina Aquarium at Pine Knoll Shores, where it received rehabilitative care.

At four months old, Harold was transported to the Pittsburgh Zoo & PPG Aquarium for further rehabilitation. As part of the Sea Turtle Second Chance Program, Harold was the perfect little ambassador for spreading awareness about the plight of the sea turtles worldwide. During his time in Pittsburgh, Harold was provided many different sea turtle enrichment options—from tiny whiffle balls stuffed with food to foraging opportunities with live foods and plenty of obstacles!
Harold won the hearts of countless visitors through tours and educational programming, but most importantly, this little sea turtle got people to take action in protecting sea turtles.
While it has certainly been a joy to get to know this spunky little loggerhead for the last two years, it is an even greater privilege to have the opportunity to return Harold back to North Carolina for release near the Gulf Stream.
Upon returning to the North Carolina Aquarium at Pine Knoll Shores,Harold was tagged with a lightweight, battery-operated tracking device. The device could last for up to one year, and will transmit location data occasionally when the turtle surfaces. As part of larger studies to learn how we can help protect them, released turtles like Harold are tagged so we can track their voyages across the seas.

Sea turtle conservation is, without a doubt, a collaborative effort. Harold’s successful reintroduction into the wild (and satellite transmitter) would not have been possible without the support of the Pittsburgh Zoo & PPG Aquarium, generous contributions from the PPG Conservation & Sustainability Fund, the team effort at the North Carolina Aquarium at Pine Knoll Shores, the NC Wildlife Resource Commission, and the continued support from sea turtle enthusiasts everywhere!
