  		Fig. 1. The difference between body surface temperature and the ambient temperature ({Delta}T) during the 168 h following feeding. Filled circles represent the fasted group of snakes, open circles represent the snakes fed a small meal (10–25%Mb), and the filled triangles represent the snakes fed a large meal (26–50%Mb). *Significant difference between the small meal value and its pre-feeding value (time 0); {dagger}significant difference between the large meal value and the pre-feeding value (time 0). The dotted line represents the oxygen uptake for snakes fed a diet of 20%Mb, and the broken line represents the oxygen uptake for snakes fed a diet of 30%Mb (taken from Andrade et al., 1997Go).

  		Fig. 2. Infrared thermal image of a rattlesnake (A) prior to feeding and (B) 48 h following feeding a meal comprising 32% Mb. The scale bar shows a total range of 2.5°C, where black is the coldest temperature and white is the warmest temperature. Note the uniform increase in body surface temperature in the snake following feeding. The darkest spot in each image is the nose, where evaporative cooling leads to a significant reduction in temperature.

  		Fig. 3. (A) Individual values for the peak thermal increment ({Delta}T) following feeding at different meal sizes as a function of snake body mass. (B) Individual values for the total area under the SDA temperature curve following feeding at different meal sizes. Pearson's coefficients are shown in both graphs.
