Coi nudibranch

Goniobranchus coi


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.


This species occurs in the tropical Western Pacific Ocean from Australia to the Philippines.


This nudi is rather yellow creamy. My camera flash was not really well focused, hence the blueish color :-)
