Thorunna kahuna is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae.[1] [2]
This marine species occurs off Hawaii.
This species is translucent pinkish-white with a magenta submarginal line on the mantle. On the back foot it has two dark purple lines. The rhinophores have translucent pink stalks and orange-red clubs while the gills are orange-red with translucent pink bases. There are prominent, opaque-white mantle glands around the posterior margin of the mantle and, occasionally, in front of the rhinophores which help distinguish it from the very similar Thorunna daniellae.[3] Adult specimens are about long.[4]
This species feeds on sponges of the genus Dysidea.
