Description

The Big Bend gambusia is a small livebearing toothcarp (Poeciliidae) native only to warm springs of the Big Bend region in Texas, in the southern United States. The species grows to about 5 cm and has a stocky, yellowish body. It lives in clear spring water and eats mosquito larvae, small invertebrate life and algae. The wild population is extremely small and survives thanks to a protected captive-breeding programme; the species is critically endangered. The female gives birth to live young.
