Morphological development of barracudas ( Sphyraena guachancho and S. tome) is described, based on larval and juvenile specimens collected in the southeast Brazilian Bight. Preflexion larvae of the two species are similar, but S. tome larvae can be distinguished from those of S. guachancho by having small melanophores on the midbrain and a row of melanophores along the ventral midline of the lower jaw and isthmus. Flexion and postflexion larvae of S. tome are more slender than those of S. guachancho. Morphology and pigment patterns of S. tome are similar to those of S. borealis from the north Atlantic. whereas S. guachancho larvae are similar to S. barracuda in having a fusiform body, advanced position of the pelvic fins and a heavily pigmented tail region, but differ in having a fleshy tip on the lower jaw in postflexion and juvenile stages.
