Goniobranchus geminus, also known as the gem sea slug,[1] is a species of very colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.[2]

Taxonomic history

Until 2012 this species was known as Chromodoris geminus but was moved to the genus Goniobranchus as a result of a molecular (DNA) study.[3]

Description

Goniobranchus geminus can reach a maximum size of 5 cm in length.[4] It has four distinctive coloured lines around the mantle edge. Starting from a thin white outer line, then a light grayish line, followed by another white line and finally a bright golden yellow line.[5] The background coloration from the back is light brown to yellowish speckled with mauve ocelli circled with a white margin. The foot, clearer and with a white margin, also has ocelli. The rhinophores are yellow or purple and laminated, gills are white outlined with beige.[6]

Distribution and habitat

This sea slug lives in the Indian Ocean from Kenya to Sri Lanka and in the Red Sea and has a predilection for the external slopes of coral reefs.[4]
