 As with rates of growth , the point at which the toads become sexually mature varies across different regions . In New Guinea , sexual maturity is reached by female toads with a snout – vent length between 70 and 80 mm ( 2 @.@ 8 and 3 @.@ 1 in ) , while toads in Panama achieve maturity when they are between 90 and 100 mm ( 3 @.@ 5 and 3 @.@ 9 in ) in length . In tropical regions , such as their native habitats , breeding occurs throughout the year , but in subtropical areas , breeding occurs only during warmer periods that coincide with the onset of the wet season .
