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.

[2] The genus Jorunna is composed of roughly 15 other species of nudibranchs, which feed on a variety of sponges.

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.

[8] In addition, another compound called jorunnamycin A,[9] has been found alongside fennebricins A (1) and B (5), both of which are bis-tetrahydroisoquinolinequinones and related to two classes of anti-tumor alkaloids.
