Chromodoris willani (*)
Chromodoris willani is a species of sea slug, a dorid nudibranch, a shell-less marine opisthobranch gastropod mollusk in the family Chromodorididae.
This nudibranch is similar in appearance to Chromodoris lochi, Chromodoris boucheti and Chromodoris dianae. What distinguishes this species from the others are the white specks found on the gills and rhinophores.
Individuals in this species can range in color from dark blue to a translucent white with black stripes.
This nudibranch is found in the Western Pacific Ocean, from Indonesia and the Philippines to Vanuatu.
