Where do siphonophores live at?

Siphonophores primarily inhabit the open ocean, particularly in the mesopelagic and bathypelagic zones, which are depths ranging from about 200 meters to over 1,000 meters. They are often found in warm, tropical and subtropical waters, but some species can also be located in colder regions. These fascinating colonial organisms drift with ocean currents, relying on both their gelatinous bodies and specialized structures for buoyancy and locomotion.
