Lions have very distinctive features that allow researchers to catalog and monitor lions within an area. One feature scientists look for is the mane of male lions, this male lion has a large mane with differing colors. Other features include the color of the nose, fur color and whether there is any spots, any scratches or marks on the lion, the lion's tail, and their whisker pattern. Like every human has a unique finger print, every lion has a unique whisker pattern.
