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.
在为期 30 天的 Bion-M1 生物卫星轨道实验中，研究了厚趾壁虎（Chondrodactylus turneri GRAY 1864）的物体游戏行为。五只壁虎的游戏物体是飞行组中的一只壁虎在发射前立即取下的标记项圈。当壁虎观察到漂浮的项圈靠近，或者当壁虎独立地接近固定的项圈时，游戏行为开始，然后对项圈进行操作，接着观察它的远离。在玩项圈时，壁虎的行为表现出个体差异，表现在游戏情节的频率和数量、操作的性质以及在飞行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）玩耍，还可以与熟悉的蜕皮玩耍。在失重状态下，带有蜕皮碎片的壁虎的玩耍行为与带有项圈的玩耍行为相似，并且个体之间也存在差异。研究表明，壁虎可以用不同的物体（项圈和蜕皮）保持相似的个体玩耍水平。还发现壁虎在正常重力条件下也会玩蜕皮碎片。与失重状态相比，在正常重力下的玩耍行为很少见，并且仅限于对物体的短暂操作。
