Description

Nudibranchs in this grouping have a mantle which overlaps the sides of the foot, apart from the tail in some families. In the Superfamily Polyceroidea and the Family Goniodorididae this is often reduced to a ridge which may bear processes. There is usually a ring of external branched gills surrounding the anus towards the back of the body, but in some subgroups these gills can be located beneath the sides of the mantle (Family Phyllidiidae, Family Corambidae). Typically there are two rhinophores with lamellae which arise through the mantle towards the front of the animals.
