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]
