Another animal I admire is the Hippo. When a pack of wild dogs attack a antelope, the hippo comes charging in and protects him from the dogs. When a crocodile get ahold of a wildebeast foot and tries to drag it into the water, hippos show up and attack the crock letting go of the wildebeast.
Hippos are interesting creatures. I saw a video of one pick up what appeared to be a 10 foot croc in its mouth, and shook the thing in the air like a rat being shaken by a terrier.
That was pretty scary to me. They always looked so...docile and fat. Then I found out more people (500 a year) are killed by hippos than any other animal.
Wow.
