At MantaWatch we think photography is an immensely valuable tool. We use your photos to identify individual manta rays, assess population trends, and monitor migrations. Through photos we can also tell a story, and educate others about a cause.

National Geographic is a leader in capturing our world through imagery, and sets the standard for photographic excellence. National Geographic has been inspiring people to care about the planet through imagery since 1888.
