Dendrodoris carbunculosa (Kelaart, 1858)

Dendrodoris carbunculosa has been found at Kwajalein Atoll both on the intertidal interisland reef and on the seaward reef, where it is active at night. About eight individuals have been seen, ranging in length up to about 250mm, making it one of the largest nudibranch species found in the Marshalls. This species has a slimy secretion that is likely toxic but is at least irritating to the eyes if they are rubbed after handling the slug.

This species is easy to distinguish from a similar close relative, Dendrodoris tuberculosa, by its unspotted underside. D. tuberculosa's underside bears large and distinct spots. The picture below is captured from video.

We think the animal below is a juvenile Dendrodoris carbunculosa. It measured only about 15mm long.
