The two features that make hair a good subject for establishing individual identity are scale structure and medullary index. The scale structure involves the length, color and diameter of the hair.
The medullary shape is the layer of hair shaft where the above attributes are featured. The medullar layer is an inside layer that runs down to the center of the cortex.
All of these represent something called "competition and predation", in which the species competes for strength, or when one species coordinates attacks against a prey species, or when one species hunts another.
