*For abbreviations and each dimension, see Table 1 and Figs. 1c, 2c and 3c. The values are means ± SD (n=150) of triplicate groups. Data were analyzed using one-way ANOVA on data transformed to the arcsine of the square root. Different capital letters on the values indicate statistical significance among morphometric distances (P < 0.05). Different small letters on the values indicate statistical significance among ratios of morphometric dimension/ standard length (SL) (P < 0.05). Different small letters on ‘a’ means the smallest value, ‘b’ means larger than ‘a’ value and ‘c’ means the largest value among 3 species data.
