From: Francis & Pirjo Pellet


Dear Bill,
We found this Ceratosoma during a night-dive. It was on the gorgonian you can see in the upper picture. Is this Ceratosoma gracillimum?

Indonesia, Lembeh Straits
dive site: Nudi Falls (night-dive)
length: 80 mm
depth: 12 m
date: 27 September 2003

Thanks for the identification .

Dear Francis & Pirjo,
This certainly looks like Ceratosoma gracillimum. It tends to have longer but more quadrangular shaped lobes than C. trilobatum and lacks any sign of a mantle edge between the head and the lateral lobes.
Best wishes
