The ID on this one is not 100% certain, but some specimens match the original description pretty well. Tambja amakusana is known from at least nine specimens in the Marshalls, one from Enewetak and the rest from Kwajalein. They were found on lagoon reefs and pinnacles under dead coral from about 6 to 15 meters.
The two photos directly below are of a specimen found on the Kwajalein Atoll seaward reef on a night dive on 13 June 2009. It was in a ledge at a depth of 10m and measured 19mm.
The dark green specimen in the two photos below was one of two found under a rock on a Kwajalein lagoon reef at a depth of about 5m on 25 July 2009.
It seems to have a swollen left foot corner.
The animal below is the one whose ID is least certain. It doesn't have the blue tipped gills and only a trace of it on the rhinophores. It also has a bit of a different look to it.
The specimen in the two photos was below was unusual in possessing longitudinal dark lines along the body. It was found on a western atoll lagoon reef on 6 August 2012.
A second lined specimen was found on 7 October 2012 in a lagoon Halimeda patch. It was a monster, measuring 22mm, much larger than any we had seen previously.
