An analysis of sexual dimorphism suggests that male tigers take larger prey than females.

An analysis of sexual dimorphism in the skull of tigers found that the greatest divergence occurred in the area involving the predatory function, specifically around the muzzle; as well as with the width of the zygomatic arches, (bones on the side of the skull below the orbits;) the size of the sagittal crest, (crest on top of the skull;) and the lambdoidal crest, (at the back of the skull.) These characteristics are more robust in males, suggesting that males may take larger prey than females.
