Polycera cf japonica Baba, 1949

The small nudibranch we are calling Polycera cf japonica is uncommon at Enewetak Atoll, where we saw about 22 specimens, all under dead coral on lagoon reefs and pinnacles at depths of 2 to 15 meters. Specimen lengths were from 2 to 9mm, but most were in the 3 to 5mm range. The ID is uncertain. Photos we've seen on the web (e.g., here and here) look a fair bit different.
