"It depends on the species. Males of many species have enlarged thumb or forefinger, some have enlarged pads on those limbs, or harder spots, used for grasping the female during mating. Other species have differences in the throat sac. There is a slight difference in the side of the head of bull frogs. "

Most female frogs have larger tympani (those disks on their heads) so they can locate males more easily. The male also tends to have thumbs placed for grasping.
As for chordates, the frog possesses bilateral symmetry, a hollow spinal chord, four basic tissue varieties and complex organs
