Platydoris sanguinea
Bergh, 1905

Suborder: DORIDINA
Family: Discodorididae


Known only from the Philippines and Indonesia.


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.
