Results Measurements (mm). Mean and standard deviation (range) of seven tadpoles: total length: 18.2 ± 0.1 (17.6–18.5); body length: 6.8 ± 0.1 (6.6–7.0); tail length: 11.3 ± 0.1 (11.0–11.5); body height: 3.2 ± 0.0 (3.1–3.2); tail height: 3.4 ± 0.0 (3.2–3.5); eye diameter: 1.0 ± 0.0 (0.9–1.0); nostril diameter: 0.4 ± 0.0 (0.4–0.5); body width: 4.7 ± 0.1 (4.4–4.8); interorbital distance: 1.3 ± 0.0 (1.2–1.6); eye-snout distance: 1.6 ± 0.0 (1.6–1.7); spiracle- snout distance: 5.1 ± 0.1 (4.8–5.4); nostril-snout distance: 0.8 ± 0.0 (0.7–1.0); mouth width: 1.6 ± 0.0 (1.6–1.7). FIGURE 1. Tadpole of Physalaemus soaresi, stage 33 (Gosner 1960). (A) Lateral view, (B) dorsal view, and (C) ventral view. External morphology. ZUFRJ 7436. Body ovoid in dorsal view, wider than high (Fig. 1AB); body height 45% of body length and 67% of body width. Eyes dorsolateral with diameter 14% of body length; distance between eyes 27% of body width. Nostrils ovoid, half-way between the snout and eyes; distance from snout to nostrils 12% of body length; nostril diameter 50% of the snout to nostril distance.
