Corambe is a genus of sea slugs, dorid nudibranchs, marine gastropod molluscs in family Corambidae within the superfamily Onchidoridoidea.[2][3]
Species in this genus show a characteristic posterior notch in the notum (which is lacking in some taxa) and a characteristic gill morphology, especially the presence of ventral gills.
These nudibranchs occur in littoral and sublittoral temperate waters of the northern and southern hemispheres.
They are mostly small (between 5 and 10 mm) and rather hard to find because they are very well camouflaged. They prey on encrusting bryozoans.
In 1994 it became a synonym of Psammodoris thompsoni (Millen & Nybakken, 1991)[5] and in 1998 synonym of Loy thompsoni (Millen & Nybakken, 1991).[6]
