From the Amazon River the largest river discharge in the world to the south there are no significant freshwater discharges throughout the northeast and southeast Brazilian Coast.
Number of vertebras range from 42 to Edipucrs, Porto Alegre, p. Such intraspecific variation in migratory behavior is well known in different fish species and appears to be the rule rather than the exception McDowallChapman et al. Bilateria bilaterally symmetrical animals. September to January, spawning is related to the increase in water temperature. Although temperature could be considered as a factor to explain this latitudinal behavior, the magnitude of the estuarine systems along the western Atlantic Coast is also a good argument to explain the estuarine use.
Molecular phylogenetics reveals a pattern of biome conservatism in New World anchovies family Engraulidae. Silva reports that the number of gillrakers was the meristic character that showed the clearest pattern of longitudinal variation, with values increasing with increasing latitude.
