The object play behavior in thick-toed geckos (Chondrodactylus turneri GRAY 1864) was studied during a 30-day orbital experiment onboard the Bion-M1 biosatellite. The play object for five geckos was a marking collar that one of the geckos in the flight group removed immediately before the launch. The play behavior started when either the gecko observed the approaching floating collar or when the gecko independently approached the stationary collar, followed by manipulation of the collar and subsequent observation of its moving away. While playing with the collar, the individuality of geckos’ behavior was manifested in the frequency and number of play episodes, the nature of manipulations, and the duration of interest in play during the flight. We found that thick-toed geckos could play not only with an unknown object (marking collar) but also with familiar molting skins. In weightlessness, the play behavior of geckos with molting skin fragments was similar to the play behavior with the collar and also varied between individuals. It was established that geckos maintained a similar individual level of play activity with different objects (collar and molting skins). It was found that geckos also played with fragments of molting skin under normal gravity conditions. In contrast to weightlessness, play behavior at normal gravity was rare and limited to short durations of object manipulation.

厚趾壁虎（Chondrodactylus turneri）中的物体播放行为在Bion-M1生物卫星上进行的为期30天的轨道实验中对灰色（1864）进行了研究。五只壁虎的游戏对象是一个标记项圈，飞行组中的一只壁虎在发射前即被移走。当壁虎观察到接近的浮动项圈或壁虎独立地接近静止的项圈，然后操纵项圈并随后观察到其移开时，游戏行为就开始了。在玩领子时，壁虎行为的个性表现为游戏发作的频率和次数，操纵的性质以及飞行过程中对游戏的兴趣持续时间。我们发现厚趾壁虎不仅可以与未知物体（标记项圈）一起玩，而且可以与熟悉的蜕皮一起玩。在失重中 具有蜕皮碎片的壁虎的演奏行为与衣领的演奏行为相似，并且在个体之间也有所不同。可以确定壁虎在不同物体（衣领和蜕皮）上保持了相似的个人游戏活动水平。人们发现，壁虎在正常重力条件下也能起到蜕皮的作用。与失重相反，法向重力下的游戏行为很少见，并且仅限于物体操纵的持续时间短。
