Polydactyly in Anurans in the Tambov Region (Russia)

Georgy A. Lada

Abstract


Polydactyly in anurans is reported to have been found in the Tambov Region (Russia). Isolated cases of polydactyly in moor frog, Rana arvalis and marsh frog, Rana ridibunda are found. Mass polydactyly in common toad, Bufo bufo is detected. Anatomical types of irregular limbs, the dynamics of anomalies year after year and possible causes of polydactyly are being discussed.
