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).
