Sessilia is an order of barnacles, comprising the barnacles without stalks. They form a monophyletic group and are probably derived from stalked barnacles [cite journal |quotes=no |url=http://www.fieldmuseum.org/research_collections/zoology/zoo_sites/barnacle/pdfs/perez-losada.pdf |title=Unraveling the evolutionary radiation of the thoracican barnacles using molecular and morphological evidence: a comparison of several divergence time estimation approaches |author=Marcos Pérez-Losada, Jens T.

Brachylepadomorpha contains a single family, Neobrachylepadomorpha, while Verrucomorpha contains two families, Verrucidae and Neoverrucidae. The remaining twelve families are in the suborder Balanomorpha cite book |url=http://www.nhm.org/research/publications/CrustaceaClassification.pdf |title=An Updated Classification of the Recent Crustacea |author=J.
