Fig. 5. Height (A), width (B), volume (C) and micrographs (D) of intestinal enterocytes from the proximal small intestine of Heloderma suspectum. Values are means ±1 s.e.m., N=3 for each fasted and fed treatment. Different letters above the bars denote significant differences between means. Scale bars in D, 20 µm. Heloderma suspectum experience a significant increase in enterocyte width and volume 1 day after feeding (1DPF), and a further increase in width and volume by day 3 of digestion (3DPF). For details of meal treatments, see Fig. 2.
