Spurilla neapolitana is a nudibranch in the family Aeolidiidae. The body of neopolitan spurilla ranges in color from pink to orange, while the digestive gland ducts in the cerata, respiratory papillae of the mantle are usually grey to dark brown. Patches of opaque white pigment on the body are present in some individuals. The rhinophores are lamellate, and the cerata quite flattened (Garcia and Cervera 1985).
