Fluctuating asymmetry is characterized by subtle and random deviations in bilaterally symmetrical features, and directional asymmetry is characterized by a distribution skewed towards one side (left or right). For the analysis of both types in the skull of the companion rabbit, 45 specimens were studied. Cranial morphology was revealed by 8 sagittal and 16 bilateral (on both sides of the skull) Cartesian coordinates on the ventral level, using geometric morphometric. According to the results, there were differences between left and right configurations, located mainly on the basis. This fact may be interpreted as a manifestation of lateralized masticatory activity.
