We have seen several of these, all at night, at Melasti, Kwanji and Sidem. Although this is called Platydoris sanguinea by most sites, we have recently seen a specimen from Kosrae that better fits the original description of P. sanguinea, and it does not appear to be the same as those figured on this page.
