To untrained eye, Phyllidia coelestis can easily be mistaken for Phyllidia varicosa and vice versa. Understandable, as these two posses very similar basic form, coloration and pattern. Both have tubercles with blue bases and yellow caps.

To differentiate the two look at the dorsal pattern. If the nudibranch has a median ridge it's a Phyllidia varicosa. If it doesn't have a median ridge and the ridge forms a Y shape arrangement instead, it's a Phyllidia coelestis.

Phyllidia coelestis also shows a broader mantle margin with smaller tubercles that has no yellow caps.

And also juvenile form of sea cucumber, Pearsonothuria graffei, mimic Phyllidia varicosa
