Structural Interspecies Variability of Mammals' Hairs

The study investigates the physical properties of hairs from various wild mammalian species, focusing on the internal structures using polarized light microscopy. By examining the hairs of the Patagonian mara, brown bear, and Amur tiger, the researchers observed significant structural differences, particularly in the medulla, cortex, and keratin cuticle. These differences are hypothesized to correlate with varying physical properties, which are currently under further investigation. This research aims to enhance the comparative understanding of hair properties across different mammalian species.
