Another great video is the two koalas wrestling. You can see them sprawl, hit reversals, attempt arm drags and more. 
 Even watching gorillas fight will remind you of sumo with all the hand fighting and trying to knock each Other off balance.

I also see no difference then to now with khabibs game .... A lot of lay and pray Reply
