Phyllidia ocellata from Japan (1)

January 14, 2002
From: Yasuhiro Shirai


Dear Bill,
I found this Phyllidia ocellata at the rocky reef off Kushimoto, middle of Japan, on 25th April, 2000. This animal had something like a ring around the tubercles at the front of the rhinophores.
Do you know what it is? A parasite?

Length: 60mm
Depth: 15m
Water temperature: 17 degrees

Sincerely,
Yasuhiro Shirai

Dear Yasuhiro,
This is indeed a strange colour form of P. ocellata. I still think we have some work to do to sort out this group of animals with black rings around the tubercles. The coloured band around the tubercle is a bit puzzling. It seems to have segments on it so it is possibly a polychaete worm, either just having a rest, or perhaps living on the nudibranch.
Best wishes,
Bill Rudman.
