Snout sharply pointed but short, less than eye diameter; maxilla long, tip pointed, reaching almost to gill opening; gill cover canals of panamensis-type.

Occurs in shallow coastal waters, sometimes in large schools, and also in mangrove-lined lagoons in turbid water. On the southern coast of Margarita Island, they appear mainly in February to May at 5-7 cm SL, while larger individuals occur throughout the year in the interior of lagoons. More data needed on food and breeding.
