Identification
The slender, somewhat compressed body carries a silver stripe slightly narrower than the eye. The long, pointed upper jaw nearly reaches the gill opening. A pale area remains on the underside of the snout where dark pigment does not reach the front of the upper jaw.

Range and spawning
It spawns in schools. Some records toward the Yucatán region and the mainland Caribbean coast are less certain, and a Belize river record is explicitly dependent on correct identification. Such qualifications are useful because similar anchovies can easily be confused in regional lists.
