Hyenas

 Hyenas have pretty strong bite force;they can eat through bone.Hyenas have formidable teeth.

                          Hyenas usually attack prey from the behind.If hyenas kill a warthog or porcupine it is by attacking it as a group,not one on one.

                              Warthogs generally steer clear of hyenas because hyenas see them as a tasty snack.Wart hogs have razor-sharp tusks in the front and can defend themselves from most predators.
