Several intraspecific, morphometric differences were observed between juveniles and subadults, and adults in both species, resulting in relatively large ranges for some characters (see Table 1). The most notable differences were in the measurements of presecond dorsal length, snout-vent length, preanal length, interdorsal distance, pectoralpelvic distance, dorsal caudal-fin margin, and head, trunk and abdomen widths. The morphometry of
