They respire through the means of skin which provides an extensive surface for the exchange of gases. It is thin, richly supplied with blood and kept moist by the mucus (produced by the frog) and water. The cutaneous respiration is always carried out. During hibernation (winter sleep and the opposite of aestivation) and aestivation (summer sleep), it is the only method of respiration in frog.
