Hi, Bill,
Is this a Tritonopsilla alba? I photo it in Batam [Batam Is, Riau Islands, Indonesia] during a night dive. There were 2 hanging on 1 whip coral.

Depth : 10m
Size 2 inches

Regards,
Alice

Dear Alice,
This is the recently named Tritonia bollandi. Wherever it is found it seems to be associated with a red gorgonian. In photos on the Forum from Okinawa and Indonesia it is on Verrucella aurantia but that species seems to have a more irregular shape than your gorgonian. Perhaps the gorgonian in your photo is just another growth form.

Tritonopsilla alba is now considered to be just a white form of Tritoniopsis elegans which feeds on the leathery soft coral Lobophyton.
