Yellow, medium sized dorid, growing to aprox 30 mm in length. The mantle is rough and firm to touch, without obvious tubercles. The most distinctive feature, other than its colour, is the arrangement of the gills in a posteriorly facing horizontal fan, with a flap of mantle forming a dorsal cover [See Michael Miller's photo above].
This is possibly a southern form of the Indo-West Pacific species Doriopsis granulosa. [see that species' Fact Sheet for further discussion].
