One lion vs 20 hyenas, can this young male make it out alive?#Dynasties pic.twitter.com/teJj9YnVbl— BBC Earth (@BBCEarth) November 30, 2018
Notice in the video the lion spends much of the time fighting while sitting down. The hyena tactic is to come up from behind and castrate the lion. With two lions able to guard each others backs, that doesn’t work.
