Deep blue background colour with numerous bright yellow spots on the mantle and foot. There are also a few similar sized whitish blue spots scattered on the notum. The rhinophore clubs and the gills are dark blue with yellow dots on the inner sides of gills. Similar in appearance to H. californiensis which differs in having larger yellow spots, and in not having white spots, nor a pale blue border to the mantle and foot, and no yellow spots on the gills.
