Male-male amplexus between two amphibian families

Abstract

The amplexus between two different anuran males is observed very rarely. Therefore, here we provide the first documented observation of a long-lasting male-male amplexus between Bombina bombina (Bombinatoridae) and Hyla arborea (Hylidae) together with an overview of the data published in literature. The observed mating pattern is reported from Southern Moravia, the Czech Republic. The possible reasons for its occurrence during the mass breeding season are discussed.
