Dorsum bears numerous irregular lines of pale yellow which become small spots on central area of dorsum; between yellow lines are Indian red spots edged with black. Scattered small black to dark green flecks also occur, especially centrally on dorsum. A thin white line occurs around margin of foot. In all, the color pattern of the dorsum very closely resembles the colonies of the bryozoan Membranipora spp. upon which the animal feeds. Rhinophores bear vertical ridges. Branchial plumes 6-14 and may be seen through postero-median notch in dorsum. Labial tentacle lobiform. Can be distinguished from the similar Corambe steinbergae by the ridged rhinophores and postero-median notch in dorsum.
Typically less than 10mm in length.
Alaska, to Bahia Banderas, Mexico.
Usually found on its bryozoan prey, Membranipora on kelp.
Gulbinia pacifica
