  • The allometric growth equation y=axb where y is the particular body dimension and x is ML, log-transformed and analyzed with linear regression. r2 is the correlation coefficient, a is the intercept (initial index) and b is the slope (allometric growth factor). The allometric growth factor, b, is significant by F-test for all body dimensions except fin width and tentacle length. NS, not significant.
