The body and cerata are usually tinged with red, hence the name [sanguinea = bloody]. The cerata are relatively short and all of similar size. One feature distinguishing it from other species of european Aeolidiella are the white-tipped rhinophores. The oral tentacles and cerata are often, but not always white-tipped as well. This species has rarely been reported, and is known mainly from the west coast of Ireland, and a few sites on the Atlantic coast of France. Picton & Morrow (1994) report that it feeds on sagartiid anemones, especially Sagartia elegans, and Tardy (1969) reports it feeding on a variety of anemones, including sagartiids and Diadumene sp. It is reported to grow to 46 mm in length (Thompson & Brown, 1984).
