Peltodoris rubra is rare in the Marshalls, where so far only about 10 specimens have been recorded from Kwajalein Atoll, mostly under rocks on shallow lagoon reefs. It is likely more common, but just in water shallower than we usually dive. The specimen in the two photos below was under a large rock on a lagoon pinnacle at a depth of about 8 meters in 1982.
The next two photos show a specimen found under a rock at a depth of 5m on a Kwajalein Atoll lagoon reef on 5 July 2009.
The next two photos show one found under a large rock at a depth of about 4m on 5 September 2009.
The specimen in the two photos below was under a large rock on a shallow lagoon reef on 3 Sepember 2012.
A relatively small specimen at about 30mm from about 8m depth on the eastern seaward reef of Kwajalein Atoll.
We have also found this species in Hawaii.
