Gambusia is a large genus of viviparous fish in the family Poeciliidae (order Cyprinodontiformes). Gambusia contains over 40 species, most of which are principally found in freshwater habitats, though some species may also be found in brackish or saltwater habitats. The genus Gambusia comes from the Cuban term gambusino which means 'free-lance miner' or may be related to Spanish gamusino, an imaginary animal used in a practical joke similar to the snipe hunt.
