Doriopsilla

Doriopsilla is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Dendrodorididae.

==Description== Doriopsilla and Dendrodoris are genera which have frequently been confused, partly because both lack a radula. They feed by dissolving their sponge food externally, using enzymes, and then ingesting sponge cells without the sponge skeleton. They share this loss of the radula and method of feeding with the Phyllidiidae but look more like other Dorid nudibranchs in having a rosette of gills surrounding a dorsal anus, whilst Phyllidiidae have the gills located beneath the edge of the mantle.
