Goniobranchus albonares Rudman, 1990

Goniobranchus albonares is small with a red margin, fading to orange submarginally, and with a snow white body, rhinophores, and gills. We previously had these listed under Goniobranchus verrieri and they do in fact resemble specimens we think are that species from Hawaii. While recent books and websites usually list these as albonares, Rudman's original description reports the margin as orange, making no mention of the red and orange-yellow bands that are more like the description of G. verrieri. Theses species could use another look to clarify their differences, but for now we will follow standard practice and list them as G. albonares. We have seen these at Enewetak and Kwajalein Atolls, typically under dead coral rocks on shallow interisland reefs at depths of 2 to 5 meters but occasionally in Halimeda patches to about 30m. They are small, usually less than 10mm.

The individual below was found eating the purple sponge Chelonaplysilla violacea growing on clumps of algae in a Kwajalein lagoon Halimeda patch.
