FIGURE 5. Scatter plot showing scores on the first two principal components explaining 56.3% of the total variance. Two taxonomic groups are detected, indicating that shape variables obtained by PCA are significant discriminators. Centropomus nigrescens is represented by black circles and C. viridis by gray circles.
FIGURE 3. Phylogenetic relationships among the Centropomus 16S in Revision of the diagnostic characters of two morphologically similar snook species Centropomus viridis and C. nigrescens (Carangiformes: Centropomidae)
FIGURE 3. Phylogenetic relationships among the Centropomus 16S rRNA gene sequences found in the GenBank (March, 2020), only those sequences which overlap with the sequences from this study were selected. Relationships are based on the neighbor-joining method and the Tamura 3-parameter with a gamma distribution (shape parameter = 1). Node value support higher than 60% are shown.

FIGURE 5 in Early development of fat snook, Centropomus parallelus (Poey 1860) (Teleostei, Centropomidae) from Southeastern Brazil
FIGURE 5. Changes of body depth relative proportions to body length for Centropomus parallelus and C. undecimalis. Body length (BL) is presented in notochord length (NL) for smaller specimens (less than 4.0 mm) and standard length (SL) for larger specimens. The C. parallelus specimens, smaller than 5.0 mm, were supplied by the laboratory rearing experiments, and the larger ones were catch in the field.
