Why do the Kage's have animals in the background? I think the animals are supposed to represent some kind of virtue, but I'm not sure what.
Is there any explanation on why those specific animals were chosen?
I stumbled across this on a forum.. I could find no other references but for the most part, it makes sense somewhat.


  
  Gaara is the young buffalo with keen instincts and promise.
  Tsunade is the rampant moose that charges without hesitation.
  Raikage is the bear that holds dominance and power on top of everyone.
  Mei is the whale that protects the sea (her village)
  Tsuchikage is the ancient scripture, the scripture that possesses much knowledge and experience.
