Part of the most remote island archipelago on Earth, Papahānaumokuākea Marine National Monument supports a reef ecosystem with more than 7,000 marine species and is home to many species of coral, fish, birds and marine mammals. This includes the endangered Hawaiian monk seal, the endangered leatherback and hawksbill sea turtles. A Hawaiian monk seal naps on the beach with a rainbow on the horizon.
