Goniobranchus coi has a white body and foot, but is instantly recognizable for its distinct dorsal pattern. The outer part of the dorsum is yellow, separated from the inner light-brown part by a wavy white and black line. The mantle is brown, edged with a thin purple line. The gills and rhinophores range in color between different individuals from translucent white, through pale-yellow and light-brown.
This species reaches at least 50 mm in length.
