Özet

Sexual dimorphism, i.e., differences in morphology between sexes of a species caused by intersexual differences in the strength or direction of sexual or natural selection, is preva-lent throughout the animal kingdom. Contrary to differences in body size, little is known about sexual shape dimorphism in anurans. Here we investigated intersexual shape differ-ences in Bufo verrucosissimus (Pallas, 1814) by taking 27 linear measurements to character-ize body morphology of 23 males and 23 females. Relative to their overall body size, males had longer limbs and larger eyes, while females displayed larger parotoid glands and had wider heads. We speculate that these intersexual differences may have arisen due to dif-ferences in natural and sexual selection regimes acting on males and females, especially during foraging, mate searching, or intrasexual competition.
