Comment from Richard Willan on photo #14996
A juvenile individual that has not yet acquired any zooxanthellae in its cerata, hence they are completely white.

Individual guarding its spawn.

Comment from Richard Willan on photo #5966
An individual guarding its eggs. As far as we know, Pteraeolidia ianthina is the only nudibranch that displays brood care.

Comment from Richard Willan on photo #5370
A very juvenile individual.

White colour form.

Blue colour form.

Comment from Richard Willan on photo #2859
Able to be identified by the 2 purple rings on the oral tentacles (looks to be more in this individual, but there are 2 main rings) and multiple rows of cerata on the long snake-like body.

Comment from Richard Willan on photo #2299
A juvenile individual of the white colour form. Note the 2 characteristic purple rings on the oral tentacles.

Comment from Richard Willan on photo #2238
This is a difficult photo to be sure of because of the angle from which it was taken. However the two purple bars on the oral tentacles and the apparently lamellate rhinophores strongly suggest it is Pteraeolidia ianthina.
