Featured Species - Pecos Pupfish (Cyprinodon pecosensis)

Featured Species - Pecos Pupfish (Cyprinodon pecosensis)

This species was once one of the most abundant fishes in the Pecos River, but is now restricted to Salt Creek in Texas and just a few locations in New Mexico due to hybridization with Sheepshead Minnow (C. variegatus) and groundwater pumping. As a result, it is classified as Threatened in Texas. It has a wide tolerance for physiochemical factors su...
