Taxonomy
This species has previously been placed in the genus Glossodoris Ehrenberg, 1831, but it was recently transferred to genus Doriprismatica by Johnson & Gosliner in 2012.
Distribution
It was originally described from the Eastern Pacific, records from the Caribbean are considered the result of a recent introduction, presumably human-induced. The indigenous distribution of Doriprismatica sedna includes Eastern Pacific: from the Gulf of California to the Galapagos Islands and non-indigenous in Western Atlantic: Florida, Belize, Bahamas and Panama.
Description
The body is oval. Mantle margin is ruffled. The foot and mantle of this seaslug has three different colors at the border: white, red and yellow on the outer border. Background color is white with two colored 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.
Habitat
It was found on mangrove roots covered with sponges in Panama. Minimum recorded depth is 1 m. Maximum recorded depth is 29 m.
The diet of Doriprismatica sedna was studied by VerdÃn Padilla et al. (2010) on the Pacific coast of Mexico. By examining the stomach content and feces, they found that this species feeds exclusively on spiculated demosponges and exhibits a variable diet, which includes 17 different species: Mycale psila, Microciona sp., Myxilla incrustans, Lissodendoryx isodictialis, Haliclona caerulea, Haliclona turquoisia, Callyspongia californica, Cliona californiana, Cliona amplicavata, Cliona flavifodina, Cliona papillae, Pione mazatlanensis, Pione carpenteri, Tethya taboga, Aaptos niger, Geodia media and Dysidea uriae.
