Submissions for the 2023 REEF Discover the Sea Underwater Photography Contest are now open! All ocean photographers are invited to submit their favorite photos. It’s free to enter, and you may submit up to three photos per person in each of the following categories:

Fish Portrait: Portrait shots of fish only; may include the fish's whole body or be framed around the head only
Macro: Close up shots that make the subject appear "larger than life"
Invertebrates: Photos featuring ocean life with no spine
REEF Survey: In celebration of the 30th anniversary of the REEF Volunteer Fish Survey Project (VFSP), photos may include divers or snorkelers participating in the VFSP as citizen scientists, including conducting REEF surveys in the water, or topside survey activities such as data entry or fish ID classes.
Habitat/Seascape/Environment: Photos of an ocean environment or seascape. They do not have to be underwater but must be marine-focused, such as over/under shots, mangroves, or topside water shots.

Submissions close at noon EDT on September 18. Online public voting will be from September 19-30. First, second, and third place winners will be selected for each category. The winning photos will be featured on our social media and communications channels. Visit for rules, submission guidelines, and to see past year's winners.
