Fish

A few fish species are native to the San Pedro Mezquital River. Among these are the two surviving Characodon splitfin species, which are both highly threatened.^[3] The extinct Durango shiner (Notropis aulidion) was native to the Rio Tunal, which forms the headwaters of the San Pedro Mezquital, a Pacific slope river rising near Durango City, Durango, Mexico (Chernoff and Miller 1986). It was taken there only in 1951 and 1961.^[4]
