Hippos are bad-tempered and that's even before they opened their mouths. Their teeth are sharp dangerous for a human body. For Shirley she got lucky when in May this year she was attacked by Hippo while going to attend a burial early in morning. The hippo attacked her, tried to crush her hand with it's sharp incisors. Fortunately the hand passed the teeth to gums in the hippos mouth. She still however sustained injuries. Access the link below to watch the video.
