Abstract
Four adult toads were kept under outdoor conditions for nine years in order to observe molting behavior. Between spring and autumn, the intervals between molting shortened when the temperature was high. The intervals were shorter in females than in males. The periods between molting lengthened as the toads aged. The molting occurred more frequently on days with increased relative humidity change. Molting most often occurred between 1500h and 2100h. The toads molted two or three times during hibernation. Another observation on one-year-old toads showed that they molted much more frequently.
