Manta rays are widely distributed, migratory, and have unique spot patterning on their underside that can be used to identify individuals. MantaMatcher is the first global online manta ray database, managing manta ray sighting and identifications worldwide. Every manta ray has a unique spot pattern on their belly, that can be used to identify them over their lifetime. Any diver or snorkeler with a camera can take and upload a manta identification photo.
Researchers can also upload and organize individually identified manta rays in the regional populations they are managing. MantaMatcher also promotes collaborations by way of cross-referencing different study sites. Scientists can now examine if populations are shared between neighboring countries, examine regional and long distance movements, and examine the lifespans of manta rays.
