Nudibranchs are a group of sea slugs that have magnificent bright colors and are known around the world for that. There are really few restrictions to what color these creatures can have. Mostly they are natives to more tropical waters but actually, 178 species have been described in Scandinavian waters.

Nudibranchs are fascinating creatures –they have no gills or shell, they are hermaphrodites and communicate with chemical signals. Here you can see some of our favourite species in the North of Europe.
