Dendronotoidea
Dendronotoidea was a taxonomic superfamily of small colorful sea slugs or nudibranchs, aeolid nudibranchs.
This superfamily name is not used in the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005). Instead, most of the families that were in this superfamily are now placed in the superfamily Tritonioidea.
