Short description
Morfologia | Morfometria
Bright brown, the back is somewhat darker than the belly. The edges of the dorsal and anal fin rays are dark in the caudal section of the body. The gill and mouth cavities are dark but do not show through the skin. The stomach and peritoneum are bright. The stomach is long, 2.2-2.3 times the length of the head, but does not reach above the anus (Ref. 44791).
