Abstract: Cranial sexual dimorphism in grey wolf (Canis lupus Linnaeus, 1758) from Bulgaria has not been studied so far. Skulls from adult individuals from across the country were studied. Thirty-six parameters (35 craniodental measurements and a volumetric one) of each skull were measured. The Bulgarian wolf population exhibits weak craniodental sexual dimorphism, which is male-biased, as is typical in canids with a monogamous social system. However, the sexual dimorphism is more pronounced than in the studied more northern populations.

Keywords: canids, Canis lupus, cranium, male-biased, sexual dimorphism
