Body deep and compressed; caudal peduncle long, extremely slender; fins falcate; caudal fin large, forked; angle along anal fin base continues along upper edge of caudal fin. Large-sized individuals possess large, nearly scaleless hump behind small, depressed head; mouth subterminal, extending to front of small eye; 73-90 scales on lateral line; usually 9 dorsal rays; 10 anal rays; pharyngeal teeth 2,5-4.2. Dark olive-gray above, silver side (Ref. 86798).
Body shape (shape guide): fusiform / normal.
Inhabits swift, rocky runs and flowing pools. The hump at the back of the head directs fish to maintain position in the swift water (Ref. 86798).
栖息于迅急的多岩石的小支流与流动的潭水。 头部背面的隆起在驼背鲦鱼的平坦的头部上引导，导致水流下来而且使鱼能够在迅急的科洛勒多河中维持位置。
