Bathyphysa is a genus of hydrozoan siphonophores within the family Rhizophysidae. It has 3 species: Bathyphysa conifera, Bathyphysa Sibogae, and Bathyphysa japonica. This genus is composed of colonial organisms that consist of specialized zooids and are characterized by an elongated body, lack of swimming bells, and the presence of a gas filled float chamber (pneumatophore). The Bathyphysa species encompass the deep ocean waters and are primarily bathypelagic predators. They typically prey on zooplankton and nekton using tentacles that bear nematocysts for capturing purposes.

== Taxonomy == In 1878, marine biologist Théophile Rudolphe Studer first described the genus using samples of Bathyphysa conifera that had been wrapped around plumb lines. This discovery was followed by that of the Bathyphysa sibogae in 1908, through specimens collected on trawls during the Siboga expedition.
