Introducing the ECOCEAN Whale Shark Photo-identification Library
The ECOCEAN Whale Shark 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 analyse whale shark encounter data to learn more about these amazing creatures.
The Library 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 information. The information you submit will be used in mark-recapture studies to help with the global conservation of this threatened species.
24000+ photos collected
9500+ whale shark reports
2000+ data contributors
2000+ whale sharks collaboratively tagged
365 research days/year
