According to the observations of Szczerbak and Golubev (1986), these geckos will attack small lizards in a terrarium. The average weight of a full stomach reaches of body weight. Molting Prolonged observations of marked lizards helps to record the frequency of molting (Semenov and Shenbrot, 1986a). Approximately half of the geckos observed in 1981 and 1982 molted during the period of observation. Only one individual (a subadult male) made two molts during one season: one in the middle of July and one in the middle of August, 1981. As all molted geckos were supplied with dorsal numbers again, and since in the next year these individuals were once again without numbers, it may be stated that molting takes place more than once a year. According to our data, there are no special molting periods, since molting individuals were observed throughout our observation period. Like other geckos, Przewalsky's Gecko devours the shed skin layers (found in two stomachs). According to observations in a terrarium, molting occurs quite rapidly over the period of several hours (Obst, 1963). Teratoscincus scincus molts not less than three times during the season. According to observations in captivity, molting takes 5-6 days (Szczerbak and Golubev, 1986). Behavior As was noted above, Przewalsky's Geckos do not protect territories. Nevertheless, in the corral, distinct aggressive behavior was observed: an adult darted at an approaching young gecko and inflicted a powerful blow to its head (perhaps having bitten it); one of them emitted a short acoustic signal.
