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.

CASES OF INCOMPLETE AUTOTOMY AND TAIL REGENERATION ABNORMALITY OF THE STEPPE-RUNNER (EREMIAS ARGUTA (PALLAS, 1773)) AND SAND LIZARD (LACERTA AGILIS LINNAEUS, 1758) IN THE VOLGOGRAD REGION

The tail regeneration frequency in 55 lizards from the Volgograd region was analyzed, among which were 12 steppe-runners (Eremias arguta (Pallas, 1773)) and 43 sand lizards (Lacerta agilis Linnaeus, 1758). The following cases of tail regenerates were observed: 0) a normal tail; 1) regeneration in the distal third; 2) a tail regenerated from the middle part; and 3) autotomy near the base (the proximal third). The majority of the lizards had normal tails (60.0% of E. arguta and 83.2/57.1% of L. agilis in females/males).
