Etymology: Gila: A river flowing from Southwest New Mexico westward across south Arizona into the Colorado River.
Eponymy: Although the etymology is not explained; Cope was unsure of the ‘truer affinities’ of the species and mentions several genera to which it might belong; so perhaps its taxonomic ambiguity was a Pandora’s box: i. [...] (Ref. 128868), visit book page.

背的软条 (总数) : 8; 臀鳍软条: 8. Gila pandora can be distinguished by the following characters: lateral line with 51-67 scales; dorsal fin with 8 rays; anal fin with 8 rays; 1st gill arch with 6-10 rakers; pharyngeal teeth 2,5-4,2; slightly subterminal mouth, extending to front of large eye; rounded, fairly blunt snout; fairly deep, compressed body; deep caudal peduncle; olive-gray above; 2 dusky stripes along silver sides (darkest on large individual), upper one extending to caudal fin, lower one to anal fin; and dusky to black caudal spot. Breeding individuals with red-orange (brightest in males) anal, dorsal and paired fin bases and side of head; orange lower side (Ref. 86798).
Body shape (shape guide): fusiform / normal.
Inhabits flowing pools of headwaters, creeks and small rivers. Occurs usually near brush (Ref. 5723, 86798). Mid-water carnivore; feeds on zooplankton, aquatic and terrestrial insects, crustaceans, juvenile fish, and a limited amount of detritus (Ref. 79012).
栖息于河川源头,小溪与小河的流动的潭水, 通常在灌木的附近。
