Jorunna funebris
(Kelaart, 1858)
 
Jorunna funebris
Maximum size:  about 60 mm.

Identification:  This is a distinctive, cream dorid in which the notum is decorated with patches of slightly elevated, black papillae. The rhinophores and gills are black.

Natural history:  Jorunna funebris has only been seen near the mouth of Pearl Harbor (Hickam AFB) and at Point Panic on Oahu. The first was found on a sponge substrate near mangroves at about 0.3 m (about 1 ft). Subsequent animals were found in silty habitats, mostly under a pier. (Erik Verhoef, pers. com.) The Point Panic animals, however, were in a somewhat more exposed location. (David Rolla, pers. com.) (Note 1) It lays a white, ruffled egg mass and probably feeds on a slate-blue sponge. (Note 2)

Distribution:  Oahu: widely distributed in the Indo-Pacific.

Taxonomic notes:  It was first recorded in Hawaii from the mouth of Pearl Harbor by Spencer Verhoef on April 10, 2014.

Photo:  Erik Verhoef: about 60 mm: found by Spencer Verhoef; Hickam Air Force Base, mouth of Pearl Harbor, Oahu; April 10, 2014.

Observations and comments:

Note 1:  Although first found in early 2014, it has since become fairly common at these two sites (Erik Verhoef & David Rolla, pers. com.). Whether it's a recent introduction or is just having a "good year" is unknown.

Note 2:  One of David Rolla's Oahu photos shows an animal next to a slate-blue sponge. (see photo) Although there is no obvious feeding damage in the photo, the sponge is similar to sponges illustrated as the food of this species on the Sea Slug Forum (and elsewhere).
