Frogs start to breed when they are fully grown at two to three years old. Eggs are laid in water, usually by shorelines or shallow water. Breeding depends a great deal on the temperature. Warm weather and sunlight slow the process. Frogs prefer cooler waters.
Males arrive at the breeding pond first and begin a chorus of croaking.
Usually only male frogs croak. They do this during the breeding season to attract female frogs and to warn away other male frogs. This attracts the females. Once the females arrive the males jump onto the backs of the females and cling on with their nuptial pads. This position is called amplexus.
