Phyllidia goslineri

Phyllidia goslineri is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Phyllidiidae.

Distribution
This rare species was described from Madang, Papua New Guinea. It has also been found at Amami-Ooshima Islands, Japan.

Description
This nudibranch has a cream coloured dorsum with smaller regularly spaced brown spots and larger pale brown blotches. The small brown spots are surrounded by pale fawn colour and the overall aspect is unlike other Phyllidia species, being reminiscent of Knoutsodonta depressa, which is camouflaged to look like a bryozoan. The rhinophores are cream. The entire dorsum is covered with small rounded tubercles.

Diet
This species feeds on a sponge.
