Red-tipped Sea Goddess

The body is oval and the mantle margin is ruffled. The foot and mantle of this seaslug have three different colours at the border: white, red and yellow on the outer border. Background colour is white with two coloured bands (inner red and outer yellow) bordering the foot and mantle. Upper half of the rhinophoral clubs and tips of the branchial leaves of the gill are red. It is up to 65 mm long.

Originally described from the Eastern Pacific, records from the Caribbean are considered the result of a recent introduction, presumably human-introduced. The indigenous distribution of Doriprismatica sedna includes Eastern Pacific: from the Gulf of California to the Galapagos Islands and non-indigenous in the Western Atlantic: Florida, Belize, Bahamas and Panama.
