Participating is as easy as joining the project here https://www.inaturalist.org/projects/melbourne-sea-slug-census-january-2023 finding and photographing as many sea slugs as you can!
Please note Sea Slugs is not a taxonomic classification - it just makes it easier for non experts to get involved i.e. if it looks like a slug and smells like a slug? it may or may not be a slug, but take a photo and submit it anyway!

There are awesome sluggy prizes up for grabs and it is a fun excuse to get out and about during the cooler months.

Also please join and add your images to the Victorian Nudibranchs iNaturalist page https://www.inaturalist.org/projects/victorian-nudibranch
