Spikedace
The spikedace (''Meda fulgida'') is a species of ray-finned fish in the Cyprinidae family. It is found in Arizona and New Mexico in the United States. It lives in fast-moving streams.
==Description==
The maximum length of the spikedace rarely exceeds 7.5 cm.〔Rinne, J.N. and W.L. Minckley. 1991. Native fishes of arid lands: a dwindling resource of the desert southwest. U.S. Department of Agriculture, Forest Service, General Technical Report RM-206. Rocky Mountain Forest and Range Experiment Station, Fort Collins, Colorado. pp. 15-16.〕 It usually has a slender body, with a somewhat compressed front, and is strongly compressed at the caudal peduncle, with a fairly pointed snout and contains a slightly subterminal mouth with large eyes. The dorsal fin origin is behind the pelvic fin origin. The scales are present only as small, deeply embedded plates. The first spinous ray of the dorsal fin is the strongest and most sharp-pointed. The spikedace has seven dorsal fin-rays and typically 9 anal fin-rays. The spikedace skin is olive-gray to light brown above, with a brilliant silver side, often with blue reflections, and with black specks and blotches on the back and upper side. The breeding male has a spectacular, bright, brassy yellow head and fins.〔Minckley, W.L. 1973. Fishes of Arizona. Arizona Game and Fish Department, Phoenix. pp. 113-115.〕
