Cesarean sections are common for humans. For gorillas, a C-section is extremely rare, complicated and potentially dangerous to both the baby and mother.
As humans, we don't think twice when we see ourselves in the mirror. These wild animals have never seen a reflection of themselves, react in some fascinating ways.
It's been said there are a lot of similarities between gorillas and other primates and humans. In this case it's probably more correct to say young children, no matter what species, just like to play.
Kids will be kids and that often means loud and silly and I'm sure this gorilla has probably seen plenty. But, calling him ugly? I guess he decided something had to be done about that remark.
If you've ever been around geese, you know that they can have a foul, (or is that fowl), attitude. This curious gorilla finds out the hard way just how intimidating a goose can be.
