Jorunna funebris, (Kelaart, 1858)
Jorunna funebris, commonly called the dotted nudibranch, is a species of sea slug. It is a dorid nudibranch, which is a shell-less marine gastropod mollusc in the family Discodorididae. The genus Jorunna is composed of roughly 15 other species of nudibranchs, which feed on a variety of sponges.
This species was described from Sri Lanka. It is widespread in the Indo-Pacific region from the Red Sea and the Indian Ocean along the East African coast to Australia, New Caledonia, and Hawaii. Jorunna funebris preys exclusively on sponges in the genus Xestospongia, and as such, the sea slug's distribution aligns closely with the distribution of Xestospongia.
