Thuridilla sp. 1 (Undescribed)
Well Gordon comes up with another cutie. A member of the family Plakobranchidae it lacks cerata and instead has paired elongate parapodia on the dorsum. Like cerata, oxygen exchange takes place here.
This undescribed species is greenish in color. The edge of the parapodia is undulating with a submarginal black line and a marginal orange edge. The head is white and blue, while the sides of the body have white specks.
Like other plakobranchs it feed on algae. Gordon's photo from the Philippines adds to the species range, which up until now was only known from Reunion Island.

This new 2nd Edition is updated and reorganized, including 185 new species. Among other features, the new edition includes additional photographs of species, an identification key, and an up-to-date classification reflecting the latest evolutionary relationships. The Indo-Pacific represents the largest expanse of tropical ocean in the world, stretching from the Indian Ocean coast of southern Africa and the Red Sea to the central Pacific of the Hawaiian Islands, Easter Island and the Marquesas.
This region supports the most diverse marine fauna of any place in the world for most groups of marine organisms. The nudibranchs and sea slugs are no exception to this rule; there are about 3,000 described species of these organisms in the world and at least 40% of these have been found exclusively in the Indo-Pacific tropics. This book illustrates 2,138 Indo-Pacific nudibranchs and sea slugs, including many undescribed species.
