"Comment from Dr. Nathalie Yonow: I don’t want to catch you up in the argument over Phyllidia ocellata. I have proved that Phyllidia ocellata, Phyllidia japonica, Phyllidia multituberculata and Phyllidia undula are all good species. As far as I am concerned, this one needs a name ad should be Phyllidia sp.
Comment from Dr. Richard C. Willan: Although this is a somewhat atypical individual, it is definitely within the known intraspecific variation for Pyllidia ocellata."
