Physaliidae Brandt, 1835 Physalia Lamarck, 1801 Rhizophysidae Brandt, 1835 Bathyphysa Studer, 1878 Epibulia Eschscholtz, 1829 (taxon inquirendum) Rhizophysa Péron & Lesueur, 1807

Cystonectae is a suborder of siphonophores.[2] It includes the Portuguese man o' war (Physalia physalis) and Bathyphysa conifera.

In Japanese, it is called 嚢泳[3] (Nōei).

The typical cystonect body plan has a pneumatophore (float) and siphosome (line of polyps) but no nectosome (propulsion medusae).[4]
