This small nudibranch 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. Several more have been found at Kwajalein, Majuro and Ailinginae. Specimen lengths were from 2 to 9mm, but most were in the 3 to 5mm range. The first two shots show a specimen from Kwajalein Atoll found on 5 January 2009 under a rock at about 6m on a lagoon pinnacle reef. This animal is also figured in Gosliner et al (2018) as Polycera sp. 5.
The 4-5mm specimens in the next few shots were found on a Kwajalein Atoll lagoon reef at a depth of 7m with an egg mass on 16 February 2009.
The animal below was photographed at Enewetak Atoll in 1982.
Another Kwajalein specimen from July, 2016, one of several found on a bryozoan colony underneath an old trashed aluminum cooking pan.
The specimens below were found at Ailinginae (upper) and Majuro Atolls (lower) by Ken Cone and Beth Van Zummeren.
