Very similar to Cumanotus beaumonti. this species is apparently smaller, not exceeding 10 mm in length, and lacks oral and propodial tentacles. It also has fewer denticles on the radular teeth. Cumanotus cuenoti feeds on Tubularia, and Ectopleura dumortieri (see Tardy & Gantes, 1980). It swims by vigorous wriggling of the body and cerata. 

At present this species is known only from Arcachon, on the SE Atlantic coast of France. The larger C. beaumonti has previously only been reported from the British Isles and Norway, where it is considered to be very rare, and is reported in the Forum from the Mediterranean. Some authors have considered C. cuenoti to be a synonym of C. beaumonti, their differences perhaps being related to size.
