Rostanga lutescens is rare in the Marshalls. Three specimens were found at Enewetak and at least four at Kwajalein, plus one more observed by Stan Jazwinski at Ailinglaplap. All were under dead coral on lagoon reefs at a depth of about 5 meters. Specimens ranged from 12 to 19mm in length. Here is a link to more detailed information on this species. The first two shots below are of Enewetak specimens.
The next two photos show an 11mm Kwajalein specimen found on the night of 1 November 2008 crawling on rubble on a lagoon pinnacle at a depth of 7m.
Here is the Ailinglaplap animal photographed by Stan Jazwinski.
The specimen below was found under a rock on a Kwajalein Atoll lagoon reef at a depth of about 7m on 14 June 2009.
Sometimes they are pretty hard to spot, like this one from 5 July 2011.
They can flatten out and almost become part of the surface of the rock.
