Comparative analysis of the pulmonary wall and septum in P. nigromaculatus and B. gargarizans. Number (A), length (B), and width (C) of the sheets in the pulmonary wall and septa in the inflated lung. Area of the lattice bottom in the pulmonary wall and septa in inflated lungs (D). Area of the sheets in the pulmonary wall and septa in both inflated and uninflated lungs (E). Area of the lattice bottom (F), length of the thick folds (G), and number (H) and length (I) of the thin folds in inflated lungs. The error bars indicate the SEMs, t test, two-tailed, *p < 0.05, **p < 0.01, ***p < 0.001.
