SYDNEY SEA SLUG CENSUS - MARCH 2021 CHALLENGE
Woohoo!! We have the first ever Sea Slug Census Inter-location Challenge in March 2021! Sydney will of course be participating along with Melbourne, Lord Howe Island, Nelson Bay, Sunshine Coast, Exmouth and Vanuatu.
Did you know sea slugs make very good indicators of climate change because they are highly visible, have short lives, and are (relatively) easy to identify? URG NSW together with the Southern Cross University's National Marine Science Centre is doing a yearly research of these highly colourful animals so please join us this year! You can participate by scuba diving, snorkelling or browsing the many rock pools around Sydney.
You must be a certified scuba diver to dive OR you can participate as a snorkeler or browsing the rock pools.
You need an underwater camera (or waterproof camera for snorkeler).
You can participate as an individual or as part of a dive team.
Dive/snorkel site scope is Sydney; Geographic range from Port Hacking to Pittwater inclusive, with Bare Island as the main census site.
Take one photo of each species of sea slug you find in the 72 hour period from 12am on Fri 12 March until 11.59pm on Sun 14 March 2021 within the dive site scope above. You don’t need to identify the slugs, just take their photos!
Crop the photos around the sea slug so it is nice and clear. Shrink the images to around 640×480 pixels so they are nice and small.
URG has been asked to help find Okenia mellita by an overseas sea slug researcher. It has never been recorded during Sydney Sea Slug Census but there's rumour it was seen around Sydney in July last year. If you do encounter it, please take a note of its location and depth and let us know.
