The common names of this genus are ridged frogs and grass frogs.[1] This type of family have many different characteristics such as the species, Ptychadena neumanni who have long hindlimbs and a large ear drum compared to the Ptychadena erlangeri, for example.[3] They also have a unique bone structure which is a fusion between the presacral vertebrae and sacrum.[4]
