Description
Brevidens has a maximum total length of 25 cm (9.8 in). This taxon is distinguishable from other genera in this family in having a very small fourth tooth on the lower mandible, which has a clear gap between it and the other teeth. It also has a distinctive pattern of four horizontal black stripes along the body. Other features of this genus include three premaxillary teeth. In adults the mouth is subterminal with a red spot on the upper lip, and there are 16 rows of scales around the caudal peduncle. The body is fusiform and low, with a straight profile at the origin of the anal fin.
Range & habitat
Brevidens is widespread throughout much of tropical South America, south to Argentina. It is a benthopelagic fish which is migratory within river systems, and found in fast-flowing water, being commoner in small tributaries than in the main channels.
In human culture
Brevidens means "short tooth", an allusion to the short fourth tooth on the dentary, a diagnostic character of this genus. The specific name, striatus, means "striped", a reference to the longitudinal dark and pale stripes along the body of adults of this species.
