On Anomalies of the Caudal Regeneration and Autotomy in Mediodactylus danilewskii (Reptilia: Sauria: Gekkonidae)


The paper presents data on the findings of three Danilewski’s gecko (Mediodactylus danilewskii) individuals with bifurcations of their regenerated tails in the Karadag Reserve (the southeastern Crimea). Possible causes of such an abnormality are discussed.
