Beautiful shiner

== Description ==
The beautiful shiner is one of the smaller species of Arizona native fish, reaching lengths of only 3.5 inches. They have pointed snouts with compressed heads and bodies, giving them a very slender appearance. Their lateral lines are slightly curved with 30 to 40 small scales. Shiners also have a lower number of fin rays, which can distinguish them from longfin daces or suckers. The dorsal and pelvic fins have only eight fin rays, with anal fin rays ranging from eight to 9. Shiners have pharyngeal teeth than line up in single lines inside their mouths, which also make them easily distinguishable. Coloration patterns include either orange or bright red bodies, with silvery gray lateral lines along their scales. Melanophores line the dorsal portions, giving them the opportunity to change colors while mating. During mating, the males will turn their caudal fins yellow or orange, for certain unknown sexually selective reasons. Males can sometimes have either bluish or red heads.〔Abarca, F. J. 1991.
