Similar to the growth rings within a tree trunk, the mane of a lion is an excellent indicator of age! The longer and darker the mane gets, the older the lion will be. It is very possible that the appearance of a lion’s mane is a sign of dominance and can actually help attract a potential mate!
Some have even pointed to the fact that a fuller mane provides protection for the neck during battle. This awesome photo was taken by @charlysavely in South Africa! 🦁
