Poecilia is a genus of fishes in the family Poeciliidae of the order Cyprinodontiformes.[2] These livebearers are native to fresh, brackish and salt water in the Americas, and some species in the genus are euryhaline. A few have adapted to living in waters that contain high levels of toxic hydrogen sulfide (H
2S)[3] and a population of P. mexicana lives in caves (other populations of this species are surface-living).[4]
Some common and widespread species are often kept as aquarium fish, while other have very small ranges and are seriously threatened.[3] Species in Poecilia are called mollies (e. g. P. sphenops) or guppies (e. g. P. reticulata) depending on body shape.
Micropoecilia has been proposed to be included as a subgenus of Poecilia.[5]
