Hi Bill and everyone!
Nice to see Platydoris inframaculata in the spotlight. It amazes me the colour variations of this animal. Yet the ventral view is amazingly similar!

Locality: Mooloolaba, Sunshine Coast, 20 m, Queensland, Australia, Pacific Ocean, 21 August 2004, Subtidal. Length: 85 mm. Photographer: Gary Cobb.

Cheers,
Gary

Thanks Gary,

Without the colour pattern on the underside I would have been reluctant to identify the orange animals in the previous message as this species. However the colour pattern on the underside needs to be treated with caution as I am sure I have collected animals which are this species, which lack any trace of this colour pattern. When present, even in a very 'faded' state,  the pattern appears to be a reliable species indicator, but when absent, it absence can mislead us into thinking it is another species.

Best wishes,
Bill Rudman
