For the study of the radiographic osteology of the Pipa pipe frog, six adult specimens apparently in good health and kept in captivity were used. The MinXray® HF 100 X-ray equipment was used to obtain the radiographic images, analyze the radiographic characteristics and determine the size (length and width) of the head, post-cranial skeleton, shoulder girdle, anterior and posterior limbs. These frogs present the pre-sacral vertebrae I and II fused, and the sacrum fused to the thin urostil. Pipa pipe scapular waist is pseudo-firmisternal. It was possible to identify the bones that make up this region, including the coracoides. The relation between the measures of the tibial-fibula length added to the length of the foot with the corporal length corresponded to 85%.
