Similar in shape and colour to Archidoris montereyensis there are a few external differences which can be used to identify them. In Peltodoris nobilis the gills are white-tipped and black or dark brown pigment, if present, does not occur on the tubercles. In Archidoris montereyensis the gills are the same yellow colour as the mantle and dark pigment often darkens some of the tubercles. See Bruce Wight's message comparing the two species.
"By the way, Anisodoris nobilis is the only one of these [sea-lemon] dorids with a distinct lemon scent. Its citrus fruit aroma is quite pleasant and usually only given off when the animal is handled." See Sandra Millen's message.
