Doriprismatica sedna is a species of colorful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.[1]


The foot and mantle of this seaslug has three different colors at the border: white, red and yellow on the outer border. The tips of the rhinophores and the tips of the gills are red in color.[2]

The maximum recorded length is 65 mm.[3]


The indigenous distribution of Doriprismatica sedna is in the Eastern Pacific Ocean from the northern part of the Gulf of California south to the Galápagos Islands.

This species was introduced to the Western Atlantic Ocean and has become established in Southern Florida and the Bahamas.[4] It also occurs in the Gulf of Mexico.[1]


Minimum recorded depth is 1 m.[3] Maximum recorded depth is 2 m.[3]
