Berthella stellata (Risso, 1826)

Berthella stellata is one of the more common pleurobranchs in the Marshalls. Specimens have been found under rocks and in ledges at night on lagoon reefs, pinnacles, and the seaward reef at Enewetak, Kwajalein, and Rongelap Atolls. Depths have ranged from 2 to about 15 meters. Lengths of 31 measured specimens ranged from 6 to 18mm. We also saw these on shallow reefs in Hawaii.

This pair was under a rock on a shallow lagoon reef on 15 August 2010.
