About SEASLUG.WORLD

One of the world's largest community-driven sea slug databases, with 2,115 species currently indexed. Strongest in the Indo-Pacific (especially Japan), growing global.

AI matches are k-NN lookups over a pgvector index of contributor photos — a similarity ranking, not a confirmed ID.

Your photos remain yours. Demo uploads are used only for identification — not stored on disk, not shared, not republished.
