Notaspidea, also known as the sidegill slugs, was a suborder which included both sea slug[disambiguation needed ]s and sea snails or false limpets, marine opisthobranch gastropod molluscs in the subclass Orthogastropoda.

Adult notaspideans are carnivorous or feed on dead matter. Their anatomy is characterized by a single, external ctenidium (respiratory apparatus) on the right side, rolled rhinophores, and a flattened shell.

The families Tylodinidae and Umbraculidae show large limpet-like external shells and a small mantle, while the species in the family Pleurobranchidae have a prominent mantle and an internal shell that becomes reduced or is lost in adults [1]. Many species produce mantle secretions as a chemical defense against predators [2]

Families

However, in the newer taxonomy of Bouchet & Rocroi (2005), the families Umbraculidae and Tylodinidae belong to the superfamily Umbraculoidea Dall, 1889, part of the clade Umbraculida. Grande et al. (2004) found Umbraculoidea to be a sister clade to the Cephalaspidea (Acteonoidea excluded).[3]
