Special thanks to the 8 teams or individuals who braved the chilly waters in between lockdowns to submit photos of 57 different sea slug species, from Port Phillip Bay to far east Gippsland. Capturing data from different times of the year, including during winter, helps us gain a better understanding of our southern sea slugs and their occurrence in space and time.

Smoke from the recent bushfires had severely impacted much of the Victorian coast this weekend, but around 100 intrepid nudi hunters made the best of conditions and submitted over 200 photos to the Census.

Thanks to everyone who submitted to our first true summer edition of the Census.

What can we say other than we were blown away by the number of nudis spotted this time! 88 species to be exact, some new additions to our records and a few entries that left our experts pleasantly surprised. October certainly seems like a busy time for both our nudis and the keen citizen scientists who search for them!
