Rubramoena rubescens may reach a length of 18 mm. The upper half of the rhinophores and oral tentacles are white. The lower half are often covered with dark brown pigment. The white-tipped cerata are somewhat disorderly organized. They are usually white-spotted with a base color of orange or brown. The base of the cerata on adults may take a reddish shade.


Most records are from shallow subtidal areas, from 10-30 meters. The diet seems to consist mainly of hydroids.


There are registrations from the coasts around the North Sea, including Norway, the British Isles and Holland.
