A lot of them take on the colors of their food by incorporating the pigment into their skin (for camouflage). Some may also be brightly colored to warn off predators.
True, Machi; I wasn't very precise in my language. Isn't it amazing how much more colorful nudibranches are than land slugs? We have plenty of those and there's no one who would call THEM beautiful. There must be some sort of survival advantage to the sea slugs' colors.

It is a sea slug :) Nudibranchs are sea slugs. It's kind of a more general group of slug-like mollusks
