How it works

The Wildbook for Whale Sharks photo-identification library is a visual database of whale shark (Rhincodon typus) encounters and of individually catalogued whale sharks. The library is maintained and used by marine biologists to collect and analyze whale shark sighting data to learn more about these amazing creatures.

The Wildbook uses photographs of the skin patterning behind the gills of each shark, and any scars, to distinguish between individual animals. Cutting-edge software supports rapid identification using pattern recognition and photo management tools. You too can assist with whale shark research, by submitting photos and sighting data. The information you submit will be used in mark-recapture studies to help with the global conservation of this threatened species.
