About SEASLUG.WORLD
Found a sea slug on a dive and came home without knowing what it was? Sea Slugs of the World is the official app of seaslug.world, a community-built field guide grown from the contributions of 630 divers, snorkelers and researchers. It covers more than 2,200 species and over 50,000 photographs. ■ A guide you search by sight Search by scientific or Japanese common name, or narrow down by colour, the region where it was observed, and taxonomy (family and genus). Even when you have no name to go on, you can get there from what the animal looked like. ■ AI identification Pick a photo and the AI proposes candidate species with similarity scores. Straight after the dive, while it is still fresh. Tap a candidate to open its full entry in the guide. ■ Works offline Save the guide data and cover photographs to your device and it keeps working on the dive boat, on a remote island, in airplane mode. ■ Updated daily New species descriptions, digests of recent papers, and photographs the community posted today. Premium membership (JPY 500 / month, auto-renewing) - Save the entire guide offline - Unlimited AI identification (the free tier has a usage limit) - Unlimited access to members-only articles - No ads Payment is charged to your Apple Account.
