See text Discodorididae is a taxonomic family of sea slugs, specifically dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea.

[2] Species in this family belong to the cryptobranch dorid nudibranchs, i.e. they are able to retract their gills into a gill pocket (cryptobranch = hidden gills).

Most are thought to feed at night on sponges, while during the day they search for dark areas or remain hidden under rocks.

One example of a discodoridid is the "Pacific sea lemon" or "speckled sea lemon", Peltodoris nobilis, which occurs off the coast of British Columbia to Baja California from low-tide waters to a depth of about 200 m. Not only is this species yellow with a bumpy surface, but it also gives off a strong fruity citrus smell when handled, adding to its resemblance to a lemon.
