Jorunna funebris, commonly called the dotted nudibranch, is a large species of sea slug. It is a dorid nudibranch, meaning it 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.[3]
Distribution
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 and New Caledonia.[4][5] Jorunna funebris preys exclusively on sponge in the genus Xestospongia, and as such, the sea slug's distribution aligns closely with the distribution of Xestospongia.[6]
Chemistry of Jorunna funebris
This species contains a chemical compound called "jorumycin," which shares the same tetrahydroisoquinoline[7] backbone as an anti-tumor drug called Zalypsis, or PM00104.[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.[10]
