This one is beautiful AND informative. Three minutes in I learned that one lion's territory here is the size of Switzerland. The five males are even called by one observing scientist - Five Musketeers. And one of their mothers is 17 years old, which is very old for a lion in the wilderness. Which means she's an incredible hunter. And her passing was really hard to watch.
And humans killed the last adult male desert lion. Now it's up to those 5 boys.
