A comparative analysis ofthe morphological features of the Caspian Bent-toed Gecko in the urbanized territories of the Absheron peninsula has been performed. was established that the tails of geckoes living on the Caspian coast are shorter than in geckos liing in residential buildings. Due to the fact that movement and nutrition of the gecko inhabiting urbanized areas occur on yertical surfaces (on the walls of houses) elongation of the tail plays an important role in balancing the body of the animal. Along with the elongation of the tail, a change in the density of the scaly cover was also noted. Thus, in the gecko living on the Caspian coast, the number of scales in the scaly cover of the lower part of the trunk is larger than in the gecko of urban areas, which on hot days protects the body of animal from overheating by hot sand.
