Sphyrna leaeini (all classes) Regression of 12 morphological measurements against PL in all S. leaeini individuals recovered seven cases of isometric growth and five cases of allometric growth (Table 4). R 2 values varied from 0.39 (KC; Table 4) to 0.85 (EE; Table 4). The measurements PS, KC, UL, CH and EE all showed significant negative allometry (Fig. 4; Table 4). Sphyrna leaeini (class-specific) Regression of 12 morphological measurements against PL in S. leaeini Class One individuals recovered five cases of isometric growth and seven cases of allometric growth (Table 5). R 2 values varied from 0.16 (KC; Table 5) to 0.78 (UL; Table 5). The measurements FS, PS, KC, DL, UL, PF and EE all showed significant negative allometry (Fig. 5; Table 5). Regression of 12 morphological measurements against PL in S. leaeini Class Two individuals recovered five cases of isometric growth and seven cases of allometric growth (Table 6). R 2 values varied from 0.08 (KC and UL; Table 6) to 0.75 (EE; Table 6). The measurements LS, PS, KC, UL, LL, CH and EE all showed significant negative allometry (Fig. 6; Table 6).
