Functional skull asymmetries in Carollia perspicillata (Phyllostomidae Gray, 1825: Carollinae)

Analysing asymmetry in wild or domestic species enables the evalu-ation of the morphological responses to functional requirements and/or stress. This report is a study of the cranial asymmetry of Seba's short-tailed bat Carollia perspicillata by means of geometric morphometric techniques. We st...
