Distribution

This species was described from New Caledonia. It is found throughout the Indian Ocean as well as the Western Pacific Ocean from the intertidal down to 30 m (98 ft). [4] [5]

Description

Goniobranchus geometricus is a small nudibranch which may grow to a total length of 35mm. It is variably coloured, with the ground colour ranging from a creamy brown to purple, The mantle has numerous cream-coloured bumps and has a white margin. The gills and rhinophores are white to greenish. [5] It is very similar to Goniobranchus conchyliatus but has green-grey rhinophores and gills whilst G. conchyliatus has red ones. [4] [6] [7]

Ecology

This animal feeds on the sponge Chelonaplysilla violacea . [8]

Chromodorididae, or chromodorids, are a taxonomic family of colourful, sea slugs; dorid nudibranchs, marine gastropod mollusks in the superfamily Doridoidea. “Chromodorid nudibranchs are among the most gorgeously coloured of all animals.” The over 360 described species are primarily found in tropical and subtropical waters, as members of coral reef communities, specifically associated with their sponge prey. The chromodorids are the most speciose family of opisthobranchs. They range in size from <10mm to over 30 cm, although most species are approximately 15–30 mm in size.
