Distribution

Hypselodoris obscura.jpg

This nudibranch was described from Port Jackson, Australia. It is a warm temperate species only found in Southeastern Australia. It is related to the widespread tropical species Hypselodoris infucata and the similar Australian species Hypselodoris saintvincentia . [4]

Description

Hypselodoris obscura has a mottled appearance due to a grey or grey-blue background colour with yellow and black spots, which vary considerably in size between individuals. There is a paler stripe down the midline. The edge of the mantle is pale blue alternating with yellow. The gills and rhinophores are bright red. [4]

Chromodorididae Family of gastropods

The 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.
