Triprion spinosus
The adult male frog is 68 mm long from nose to rear end and the adult female frog is 80 mm long.  It has large, bony head with spines on it. In adult frogs, the skin has partially grown into the bone.  Younger frogs do not have this.  These frogs are dark brown in color, black bellies, and white sides.  Male frogs do not have vocal slits in their throats, but they can sing anyway.
