It is possible these are a variety of Ceratosoma gracillimum, but they differ in the ruffled edges of their lateral and dorsal lobes. We saw these at dive sites Retak Larry and Nudi Falls.
The specimen at Retak Larry was on a night dive when the Ceratosoma was nestled up against a Glossodoris cincta, and a small commensal Periclimenes imperator shrimp was crossing back and forth between the two nudibranchs.
