This unusual species had soft tendrils sticking out of light and dark patches dorsally. My only specimen was found under a rock at a depth of 8m in the lagoon of Kure Atoll on 17 June 1980. An egg mass (not shown) under the same rock was a yellow-orange coil. This is apparently known in Hawaii only from the far northwestern end of the Hawaiian chain, with one specimen recorded from each of Midway and Kure Atolls. The Midway specimen is figured on Sea Slugs of Hawaii. Gosliner et al (2018) report it as widespread in the Indo-Pacific.
