N corresponds to the sample size, CI to the confidence interval, and SE to standard error of the b parameter. The maximum length corresponds to the total length published for each species in FishBase [20]. Values in parenthesis represent the standard error. Species endemic to the Red Sea is marked with a Y, and species endemic to the Red Sea, including the Gulf of Aden, is marked with a Y.
