The twisted body of this specimen of C. annae reveals the continuation of its brilliant color scheme on its ventral side. The external gills are extended here, but are quickly retracted into its body when disturbed. This physical feature, in which the gill plume may be retracted into the notum, characterizes this as a cryptobranch dorid. Several other nudibranchs of family Chromodoridae have similar distinctive patterns of lines along the rim of the mantle.
