SEA SLUG CENSUS
Join the excitement with URG, Southern Cross University, and iNaturalist as we host thrilling Sea Slug Census events! Held for 2 weekends every November at both Port Stephens and Sydney, these events encourage divers to capture images of various sea slug species and upload on iNaturalist to conduct the census.
Did you know there are over 2,000 known sea slugs, with many more yet to be discovered? Sea slugs are remarkable climate change indicators due to their visibility, short lifespans, and easy identification. By participating, you contribute to scientific understanding of species distribution, climate change impacts, and potentially discovering new species. Dive into discovery with us!
Participate through scuba diving, snorkeling, or exploring rock pools.
REQUIREMENTS:
-
Certified scuba divers are welcome, or you can participate as a snorkeler or rock pool explorer.
-
Bring an underwater camera (or waterproof camera for snorkelers).
-
Join individually or as part of a dive team.
CENSUS GUIDELINES:
-
Dive/snorkel site scope: Sydney, with a geographic range from Port Hacking to Pittwater, including Bare Island as the main census site.
-
Capture one photo of each sea slug species within the census timeframe and dive site scope—no need to identify them, just snap their photos!
-
Crop the photos to highlight the sea slug clearly.
-
Upload your results to iNaturalist. If you are facing challenges joining iNaturalist for the Census then let us know, and we'll ensure your observations are included.
-
Embark on this underwater adventure with us and make a splash in marine research!
