Huge, lazy big cat also known as the African lion. This guy's pretty old, because I remember him being there when I was in high school, and I'm 4 years out of grad school now. I can tell he's of the dudely persuasion because of that glorious mane.
Grasslands of sub-Saharan Africa and parts of Asia.
His name is Jonathan and he lives at the Houston Zoo...with two females, it looks like.
