An extraordinary albino individual. I have seen other Phyllidia ocellata from Thailand that are almost completely white, but never one like this.

An individual with extremely unusual coloration.

I prefer to call this Phyllidia multituberculata (the Indian Ocean species) undula (the Red Sea form).

This individual shows the very unusual colour form found in parts of Thailand without any black rings on the mantle.

An individual of the colour form without any black circles.

This is a most extreme colour form without any black markings at all. This form seems to occur only in Malaysia and Thailand.

An extraordinarily atypical individual without any black pigment on the mantle whatsoever. A second individual of this remarkable colour form is shown on page 265 of Nudibranchs of the World by Helmut Debelius and Rudie Kuiter. That individual was also from the Gulf of Thailand.

This individual displays an extreme colour form of Phyllidia ocellata where absolutely no white rings are present.

An interestingly coloured individual – looks like a mixture of the colour forms called Phyllidia babai and Phyllidia undula.

Comment from Nathalie Yonow on photo #2507
Phyllidia undula, only recorded from the Red Sea. I have seen one specimen from South Africa but nothing else. If you have any others, I would be happy to revise my ideas, but internal characteristics and juveniles of four of these species are consistently different. You only get this one in the Red Sea by the way.

The population in the Red Sea always has this wavy (instead of ocellated) pattern on its mantle and it has received the name Phyllidia undula for this distinctive pattern (so Phyllidia undula can be used as a regional form name). But this same pattern can also be found, albeit rarely, in “normal” ocellated populations in the Indian and Pacific Oceans, so Phyllidia undula cannot be considered as a species separate from Phyllidia ocellata.

Comment from Richard Willan on photo #2037
I think this individual represent an extreme colour form of Phyllidia ocellata.

Comment from Richard Willan on photo #607
A very atypical individual with no gold on the mantle.

Comment from Richard Willan on photo #51
Typical colour form.
