Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Spine anali: 0; Raggi anali molli: 14 - 17. Body fairly elongate. Snout long, about equal to eye diameter; maxilla moderate, tip rather bluntly pointed, reaching onto inter-operculum, but not to edge of gill cover; gill cover canals of panamensis-type. Anal fin very short, its origin below or behind last dorsal fin ray base. A silver stripe along flank, about 3/4 eye diameter.
A schooling species found in coastal waters. Caught over sand or gravel in the Gulf of Nicoya but not in inner parts of the Gulf. May spawn over a protracted period in Gulf of Nicoya. The eggs are oval. TL = 1.25 SL.
