Cases of defensive behavior in two species of true frogs (Аmphibia, Ranidae)
For the first time, including for the territory of Russian Federation, data are presented on the defensive behavior of the marsh frog Pelophylax ridibundus (Pallas, 1771) from the Republic of Mordovia and the Astrakhan region, which occurs in two variants, namely, with raising the body and protecting the eyes. The defensive behavior of the common frog Rana temporaria Linnaeus, 1758 from the Republic of Mordovia consists of covering the eyes with the fingers of the forelimbs and is encountered in the literature as “wintering”. A comparison with literary data is given.
