Figure 3. Radiographs of the four species of Limnonectes examined in the present study in dorsal (top row), ventral (middle row), and lateral (bottom row) views. Note the translucent caruncle and the underlying osseous bulging of the parietal bone, most pronounced in Limnonectes dabanus (arrowhead). The arrows indicate the concave lateral curvature of the anterior ramus of the pterygoid bone. Only the dorsal images are to scale. Scale bar: 1 cm.
