Environment: milieu / climate zone / distribuzione batimetrica / distribution range
Ecologia
marino pelagic-neritic; distribuzione batimetrica 0 - 50 m (Ref. 189). Tropical; 23°N - 7°N, 90°W - 61°W (Ref. 189)
Western Central Atlantic: Greater and Lesser Antilles to Trinidad; Venezuela westward to Panama and Yucatan. Not separated from Anchoa hepsetus until recently; references to Caribbean 'hepsetus' may refer to Anchoa colonensis.
Size / Peso / Age
Maturità: Lm ? range ? - ? cm
Max length : 14.0 cm TL maschio/sesso non determinato; (Ref. 5217); common length : 10.0 cm TL maschio/sesso non determinato; (Ref. 5217)
Spine dorsali (totale) : 0; Spine anali: 0; Raggi anali molli: 17 - 21. Body somewhat compressed. Snout pointed, about 3/4 eye diameter; maxilla long, tip pointed, reaching to hind margin of pre-operculum; gill cover canals of panamensis-type. Anal fin short. Anus nearer to anal fin origin than to pectoral fin tips. A narrow silver stripe along flank, about width of pupil.
Body shape (shape guide): elongated; Cross section: oval.
Forms dense schools, often in shallow waters close to shore. Probably similar to A. hepsetus in other aspects of its biology.
