Label A-Males develop vocal sacs here to dominate feeding territories
Label B - Presence of cloacal chamber with larger opening in males for sperm reception
Label C - Thickened pad develops in males to ensure firm grip on female
Label D -Muscular hindlimbs
In male frogs, a thickened pad develops on the first digit of the forelimb (Label C) during the breeding season. This pad helps males grip the female securely during mating. This is a classic example of sexual dimorphism seen in frogs — a structural modification found in males but not in females.
