The Devils River minnow is a species of ray-finned fish in the family Cyprinidae. The minnow coexists with other closely related species and other cyprinids in the range of northern Mexico and southern Texas. The Devils River minnow has its dorsal and dorsal lateral scales darkly outlined, double dashes along the lateral line, and a long dark lateral stripe through its snout and eye. It can also be characterized by a black spot on its wedge shaped caudal fin and a cross hatched appearance on its body.[5] The eye shape is round during its larval stage and can be compared to other minnow species larvae that have more of an oval shape.[2] Adults can range from sizes of 25 to 55 millimeters, or approximately one to two inches.[5] The distinct shape of the intestines also distinguishes it from other herbivore minnows.[2] The intestines of the Devil’s River minnow are more multi-looped and convoluted in the larval and juvenile stages compared to the same structures in minnows that eat insects, which are generally straight and turn into an s-shape during the larval and juvenile stages
