Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 9; Raggi anali molli: 8 - 9. Gila atraria can be distinguished by the following characters: deep, compressed body; large eye; short, blunt snout; 45-65 scales on lateral line; dorsal fin usually with 9 rays; anal fin with 8 rays; pharyngeal teeth 2,5-4,2; olive-brown to blue-black above; yellow to brassy side; clear to olive-yellow fins; and large males with yellow to gold-fin bases, mouth and side of the head, may be gold overall (Ref. 86798).
Body shape (shape guide): fusiform / normal.
Adults occur in lakes, quiet pools of headwaters, creeks and small to medium rivers. Often found in vegetation over mud or sand (Ref. 86798). Migratory behaviour is undetermined (Ref. 126106).
