Comment from Nathalie Yonow on photo #684
The up-turned posterior end of the head shield is the give-away, and the flat head.

Comment from Richard Willan on photo #911
A rather unusual individual that does not have any white spots on the head shield or parapodia.

Comment from Richard Willan on photo #1027
It is recognisable as Philinopsis cyanea by the blue band on the edge of the parapodia. Philinopsis taronga only occurs in temperate eastern Australia and northern New Zealand.

A very unusual individual that has hardly any white or orange spots on the head shield or parapodia.

Comment from Richard Willan on photo #1896
An individual that is rather dark with few orange and white spots on the head shield and posterior shield. Note the raised and rounded posterior end to the head shield.

Comment from Richard Willan on photo #1899
An individual that is rather dark with many white spots but few orange and yellow spots on the head shield

Comment from Richard Willan on photo #1900
A rather "typical" individual with many orange and white spots on the head shield and posterior shield. But because this species is so variable in terms of coloration, it is impossible to really pick out any individual that could be called "typical". Note the raised and rounded posterior end to the head shield – at least that is a "typical" character for this species.

This is Philinopsis cyanea (Martens, 1879), the colourful form! It is found throughout the Indo-West Pacific, and is variable in colour. Diagnostic is a blue margin and the upheld tip of the head shield. It feeds on other small opisthobranchs, bullomorphs!

Comment from Richard Willan on photo #3689
This individual is an example of the very sparsely spotted colour form of this extremely variable species. By contrast, Philinopsis gardineri would have a bulbous head and the posterior of the head shield would have a thin white marginal line.

Comment from Nathalie Yonow on photo #11500
The blunt head end and standing up tail end are a give-away. Comes in a huge range of colours.

Comment from Nathalie Yonow on photo #24436
Short and chunky compared to gardineri, with the orange markings faintly visible on the front of the head.

Comment from Richard Willan on photo #29283
This one from temperate eastern Australia is a very dark colour form of Philinopsis cyanea.
