The Portuguese man o' war (Physalia physalis), also known as the man-of-war [6] or bluebottle, [7] is a marine hydrozoan found in the Atlantic Ocean and the Indian Ocean.It is considered to be the same species as the Pacific man o' war or bluebottle, which is found mainly in the Pacific Ocean. [8]
The family Physaliidae is monotypic, consisting of only one genus, Physalia [2].The genus is also monotypic, containing only P. physalis. [1] [3] There is a long history of the genus being described with multiple species, such as the Pacific man o' war (P. utriculus), however most of these species are now considered synonyms for P. physalis.
Physalis (/ ˈ f aɪ s ə l ɪ s /, / f ɪ-/, / f aɪ ˈ s eɪ l ɪ s /, /-ˈ s æ-/, from φυσαλλίς : phusallís 'bladder' [3]) is a genus of approximately 75 to 90 flowering plants in the nightshade family (), which are native to the Americas and Australasia.
The highly apomorphic Siphonophorae—like this Portuguese man o' war (Physalia physalis)—have long misled hydrozoan researchers. The earliest hydrozoans may be from the Vendian (late Precambrian), more than 540 million years ago. [5] Hydrozoan systematics are highly complex. [6]
Portuguese man o' war (Physalia physalis) Organisms in the order of Siphonophorae have been classified into the phylum Cnidaria and the class Hydrozoa. [3] The phylogenetic relationships of siphonophores have been of great interest due to the high variability of the organization of their polyp colonies and medusae.
Physalis peruviana is a species of plant in the nightshade family native to Chile and Peru. [2] Within that region, it is called aguaymanto , uvilla or uchuva , in addition to numerous indigenous and regional names.
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]
