Fig 1. Relationships between snout-vent length (SVL) and mass, fat, and true body condition measures for male and female Burmese pythons.

The SMA regression of log-transformed body mass on log-transformed snout-vent length (A) and of log-transformed fat mass on log-transformed SVL (B) shows the allometric relationship among these variables. As measures of true body condition, OLS regressions of percent fat on log-transformed SVL (C), scaled fat on log-transformed SVL (D), and residual fat on log-transformed SVL (E) should have zero slopes, but they do not. Significance for the regression slopes and r² values can be found in Table 3.
