An eastern Pacific species, its distribution ranges from Gulf of California to Ecuador (including the Galapagos Islands) and is a suctorial-feeding carnivorous gastropod inhabiting hard surfaces from -10m down to about -100m deep. A locally comm.on species, the shell length averages at about 30mm. but extremely large examples may exceed 40mm. The strength of sculpture is somewhat variable but overall it is a little-varied and easily recognised species.
