Template:Short description Template:Speciesbox The Cuban gambusia, spotted gambusia or blue gambusia (Gambusia punctata)[1] is a species of freshwater fish. It is a member of the family Poeciliidae of order Cyprinodontiformes, and is the type species of its genus.[2] It is native to Cuba, inhabiting lakes, ponds and streams, including mountain streams. A carnivorous surface feeder, it occurs in shoals near the shoreline. It be found in estuarine habitat.[3][4]
This species has the terminal, upward-facing mouth typical of surface feeders, and a protruding belly. It has four or five rows of darkly spotted scales, possibly forming a dark lateral stripe in the case of the midline row. The dorsal and caudal fins are typically partially spotted.[4] Males reach a maximum standard length (SL) of around 4.8 cm, with females reaching about 7.0 cm.[5] Record SL for this species is 10 cm.[3]
Gambusia punctata is part of a species complex including G. rhizophorae, G. xanthosoma, G. beebei and G. pseudopunctata.[6] Additional cryptic species have been proposed to exist within the range of G. punctata on the basis of mitochondrial haplogroup data.[6][7]
