Get Started

Thank you for showing an interest in SharkBase. With your help, we hope to use the data gathered to map the distribution and abundance of sharks* globally, and use this information to infer patterns of marine ecosystem health.

Whether you have personally encountered sharks or not, you can contribute to SharkBase. Here are 7 ways that you can help and become a Citizen Shark Scientist today!


  1. Log your past, present, and future shark* encounters with SharkBase.

    • Shark* Photos: If you have photos of sharks* on your computer, you can log these as long as you know the date and location they were taken. You don’t even need to know the species, as our scientists can identify them for you.
    • Dive Log: You don’t need a photo of a shark* to log an encounter. If you have a shark* sighting recorded in your dive log or trip diary, then you can submit this sighting (as long as you know the species, date, and location of the encounter).
  2. Log other people’s shark* encounters with SharkBase.

    • Sharks* Online: Everyday, thousands of photos and videos of shark* encounters are uploaded to the internet. You can log these sightings as long as you know the date and location of the sighting. When you log an online sighting, simply type the web address of the source material (ie: YouTube link or Google image, etc.) into the URL field so that our scientists can verify the sighting and remove duplicates. Why not give it a try, search Google News for 'shark sighting' and see what you find. For more specific results you can also include a location and date in your search.
  3. Verify SharkBase Sightings.

    • Identify Sharks*: Every month, we recieve hundreds of sightings to SharkBase, and, although our team of experts makes every effort to verify the accuracy of these sightings, sometimes we don't get it right. This is why we need your help. If you would like to participate in SharkBase, but you don't have any sightings of your own to submit, then, you can help us by verifying the accuracy of sightings submitted by other users. Go to Verify Sightings to get started.
  4. Encourage dive clubs and tourism operators to log their shark* sightings with SharkBase.

    • Clubs and Societies: Dive clubs and tourism operators working on the water come into contact with sharks* regularly, and so by encouraging them to use and promote SharkBase, we can access shark* encounters from all over the world. Every month, the club/society that is affiliated with the most sightings will be promoted on our social media pages, reaching more than 100,000 people. Please contact your local dive club or tourism operator and see if they would be willing to display a SharkBase Poster and/or Pamphlet, and encourage their members to get involved.
  5. Conduct a project using data from SharkBase.

    • SharkBase Project: You can use SharkBase to collect data for your project and contribute to our global database at the same time. Following Step 2 above, search the internet for shark* sightings around the world, or from a specific region, and compare your results between species, dates, or locations, etc. Use your personal sightings log to store and map your data.

    • SharkBase Collaboration: Are you a scientist interested in using data from SharkBase in your research project? We would love to hear from you to discuss how we can collaborate on your project. For more information, see 'Data Sharing' on the About page.
  6. Give a SharkBase talk/workshop at school/work and encourage your friends to get involved.

    • SharkBase talk: Feel free to use any information on the Support Our Sharks website, including our free films, to put together a short talk about the importance of the SharkBase Citizen Science project. Following your talk, you can run a workshop where you get everyone to register on SharkBase and then search the internet for shark* encounters to log (as described in Step 2 above).
  7. Share sightings from SharkBase on social media.

    • Social Sharks*: SharkBase relies on the help of Citizen Scientists, like you, to ensure a constant flow of new data. By sharing SharkBase images with your friends, you will be helping to encourage more people to participate and become Citizen Shark Scientists.
