Distribution and protection state of Coronella austriaca (Reptilia: Serpentes: Colubridae) in Kazakhstan

The smooth snake (Coronella austriaca Laurenti, 1768) was known in Kazakhstan from literary sources and reptile collections by few findings within the boundaries of the modern Aktobe region in 1871–1956. The paper gives the coordinates and dates of the 2019–2022 findings in the West Kazakhstan region, where this species has not been met before.

Authors: Klenina A. A.

Characteristics of the meristic features of the external morphology of young and adult snakes (the Colubridae family) of three species, namely, the grass snake Natrix natrix, the dice snake N. tessellata and the Pallas’ coluber Elaphe dione, living in the Samara region, are described. For the first time, a comparative analysis was carried out of a number of morphological characters of unevenaged snakes, namely: newborns obtained in laboratory conditions, juvenile specimens, and adult snakes captured in nature.
