A semi-transparent, white body and orange, red-brown or brown cerata seem to be the most common color combinations, but color cannot be used as identification as the cerata may take a wide range of colors. The rhinophores (tentacles on the head) have small warts. This feature can be used to distinguish it from the F. verrucosa. It can grow to a length of 4-5 cm.


It seems to thrive on rocky, current-exposed locations with a lots of hydroids to feed on.


This is an Arctic species, widespread in the North Atlantic Ocean, including Ireland and Norway.
