Join eShark
We want to collaborate with you. Whether you’re a field observer, dive guide, NGO, researcher, business owner, sponsor, or storyteller — everyone can contribute.
A monumental collaboration.
eShark has already helped protect 100+ shark and ray species and 19+ million km² of ocean. With the eOceans app, this collaboration now runs continuously — across all species, all places, in real time. Join us!
All hands on deck

Field observers
If you know your sharks and rays (or most of them), keep an eye out for them and the threats they face, and share your surveys with us:
🌀 Download the eOceans app (iOS, Android)
🌀 Explore and survey your sites, anywhere
🌀 Log your shark & ray observations — including zeros!
🌀 Log threats — lost fishing gear, pollution, etc.
As you add observations, they are checked by scientists and then transformed into results in real-time.
Become a Partner, Influencer, or Sponsor:
Partners and sponsors help scale eShark by spreading the word — while gaining visibility, credibility, and measurable impact.
eShark is led by the experts behind globally influential shark and ray science:
🌀 100 million sharks killed each year — threatening populations, livelihoods
🌀 Global manta rays and manta-driven tourism is threatened by IUU fishing
🌀 The Great Fiji Shark Count, eShark Thailand, eManta, and more.
🌀 Sharks disappear on reefs close to human populations, unless strong tourism and conservation
🌀 Shark Sanctuaries have many benefits for sharks and rays, but don’t address all threats
🌀 Yellow stingrays are declining throughout their range, unnoticed by science
🌀 Many more (see impact page for details)
