Locality: Kofiau Island, 7 metres, Raja Ampat Islands, Indonesia, Pacific Ocean, 23 February 2007, Rubble. Length: 3 cm. Photographer: Erwin Kodiat.

The body is flat and the mantle broad and stiff like all species of Platydoris. The gill pocket is raised and 6-lobed, one lobe for each of the six tripinate gills. The mantle is a dark red, or reddish brown, with a few small white spots. The gills are translucent white with brown pigmentation on the outer face. The underside of the mantle is translucent white and the sides of the body are reddish brown. The largest specimen reported by Dorgan et al was 41 mm long preserved, suggesting this species may not grow as large as most in the genus.

Hi Bill,
I found this nudibranch at Raja Ampat on a night dive. Can you help me ID this? Thanks

Dear Erwin,

I am pretty sure this is Platydoris sanguinea but it always helps with these flat dorids to turn the animal over and take a photo of the underside as well.  Apart from giving me an idea of its colour it also helps to give an idea of just how soft or stiff and 'leathery' the mantle is. When we haven't many external characters to go on every little bit of extra information helps

Best wishes,
Bill Rudman
