Gymnodoris plebeia (Bergh, 1877)

Gymnodoris plebeia was moderately common at Enewetak Atoll with more than 50 specimens found. It is less common but still present at Kwajalein. Most were seen on lagoon reefs and pinnacles, under rocks during the day or out crawling in the open at night. Thirty measured specimens ranged from 6 to 20mm in length. Larger than about 12mm long (the two bottom photos), they seem to become more high-sided rather than tubular and the gills seem to expand. The radula of both "forms" is very similar, so we assume they are all the same species.

The innards clearly show through the mostly transparent skin.

The specimen below just finished laying down a mass or orange eggs.

The specimens below were all relative large for the species, between 12 and 20mm.
