Cystonectae (from Ancient Greek κύστις (kústis), meaning "bladder", and νηκτός (nēktós), meaning "swimmer") 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
