eShark has collected scuba divers, snorkelers, and other observations on sharks and rays from around the world! These data have helped get sharks and rays on the endangered species list, supported smarter Shark Sanctuaries, informed species status on the RedList, and united communities around the world to track and protect sharks. eShark was rigorously developed through collaborations with divers, statisticians, biologists, and experts in the field of citizen science. eShark is led by Dr. Christine Ward-Paige, who has specialized in crowdsourcing ocean data with a focus on sharks and rays. When you log your observations in the eOceans platform they automatically go to eShark global, but they can also go to many other shark projects in the platform if you "JOIN" them — so your one observation can help one or many projects automatically. For the ocean. For us.
