First record of a male-male aggressive interaction in the golden Alpine salamander Salamandra atra aurorae (Caudata, Salamandridae)

Abstract

The golden Alpine salamander Salamandra atra aurorae Trevisan, 1982 is an endemic subspecies found in Sette Comuni and Vezzena plateau in Veneto, Italy. We describe an aggressive interaction between two males which fought for four minutes, trying to go on top of each other and rubbing their chin on the antagonist’s head. This is the first documented case of aggressive behaviour in Salamandra atra aurorae.
