Relative growth rate of dentary compared with body length for six species: cyan dots = barracouta (BAR), Thyrsites atun; blue dots = blue cod (BLU), Parapercis colias; yellow dots = snapper (SNA), Pagrus auratus; green dots = kahawai (KAH), Arripis trutta; red dots = red cod (RED), Pseudophycis bachus; and red dots also = albacore (ALB). These species belong to quite different families, yet follow a surprisingly similar relative growth curve. There are good grounds for expecting departure from co-linearity in the case of very large specimens of any one species. This is because the same percent variation in condition factor results in increasingly greater absolute variation from small to large (see Fig. 18).
