Wondering how to fix a mistake on your REEF survey? It depends on whether you’ve hit the SUBMIT button.
If your survey is still listed under “Surveys In Progress” (after the address confirmation screen), you can edit it yourself. Before submitting, we suggest reviewing your photos and confirming all IDs.
If you’ve already submitted your survey, no problem! Email us with the 7-digit survey number and details about what needs to be added, changed, or deleted, and we'll be happy to get it updated for you.
Ever recognize a fish instantly, without knowing how? That intuitive sense is called GISS or Jizz - short for “general impression of size and shape.” Originating from WWII aircraft spotting and later adopted by naturalists, it describes the instinctive recognition of a species through its overall look and behavior. The term "jizz” first appeared in an Irish natural history column in 1921, and is likely derived from the German word gestalt, meaning a complete shape or form. It's often used in birdwatching.
On average, more than 1,000 REEF surveys are submitted each month by volunteer divers worldwide, adding to the world’s most comprehensive marine fish biodiversity database. Since January 2024, 22,665 surveys have been submitted by 1,226 REEF volunteer surveyors.
In 2025, we’ve received several exciting new data requests from researchers using REEF data for important studies, including:
• North Carolina State University: studying South Atlantic marine life.
• Simon Fraser University: tracking Spiny Pink Sea Star trends in British Columbia.
At REEF, every survey you submit adds vital data to marine conservation, and we love celebrating your contributions! As you reach key milestones in the Volunteer Fish Survey Project, you’ll receive recognition along the way:
• 100 Surveys: Congrats email and printable certificate.
• 500 Surveys - Juvenile Golden Hamlet: Mailed certificate, webpage listing, and social media shoutout.
