Distinguishing anchovies
It resembles the European anchovy closely. Compared with western Atlantic Anchoa species, it has a shorter upper jaw with a blunt tip. A long internal gill structure, the pseudobranch, separates it from Atlantic Anchoviella in specialist keys. These features are more useful for examined fish than for distant sightings of a school.

Spawning
FishBase reports a spawning peak in July or August and describes oval, rather than spherical, eggs. Its migratory behavior remains unresolved in the cited summary. The reported coastal distribution should therefore not be turned into a specific seasonal migration route without additional evidence.
