Sexual Dimorphism in Bufo eichwaldi‘s Snout Shape with Description of Its Usage in Male-Male Competition

Omid Mozaffari, Esmaeil Saeidi Moghari


Bufo eichwaldi is a relatively large toad distributed in the Hyrcanian (Caspian) Forests from southeastern Azerbaijan to northwestern Iran. During fieldwork in northern Iran, we found two breeding sites for this species. Our observations show sexual dimorphism in the snout shape of this species that functions in male-male competition.
