Fig. 1. The difference between body surface temperature and the ambient temperature (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%M_b), and the filled triangles represent the snakes fed a large meal (26–50%M_b). ^*Significant difference between the small meal value and its pre-feeding value (time 0); 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%M_b, and the broken line represents the oxygen uptake for snakes fed a diet of 30%M_b (taken from Andrade et al., 1997).
