We've got a big bull elephant, just yards away from us.
It's been here all night.
A young male who appears to have
been kicked out of his herd, he's quick to change his mood.
I'm very nervous around this elephant.
He is a bull in musk.
He has the runny ears, the runny glands.
That's a bull in musk.
That's pretty much the most aggressive animal on earth.
When a bull elephant this in musk,
he attracts females in heat, but also produces 40 to 60 times
more testosterone, making him highly aggressive
to other elephants and humans.
Wow.
