Nimbus, a white (albino) loggerhead sea turtle, was found on a local beach in his eggshell and now lives in the North Carolina Aquarium at Pine Knoll Shores. We saw him first when he was just a hatchling, and he is now six years old. The double image is caused by his reflection as he swims near the top of his tank.
