《A skull shows its nature》

Once starting attack,the lion doesn't stop.It's said the speed of flinging itself on the prey is almost 80kilometers per an hour.It's just one of scenes that the lion drove a zebra to bay.♌

The lion caught the zebra on the back with the sharp front paw,pulled it down on the ground, mobilizing whole of the muscles.Then it bit the zebra on the throat fiercely.♌

Nerves of the zebra's neck were cut down with the lion's sharp fangs,so the zebra was dead,for its trachea 気管 was crushed.💀

The lions fangs are so sharp that they are suitable for cutting up the prey's body into pieces.In addition,the bone of its jaw supporting its teeth are thick and strong.♌

When looking at the teeth,we can recognize whether it's an herbivore 草食動物 or a flesh-eating animal.💡

《Mechanism and life of herbivorous animal》

A gnu belongs to the cattle.It inhabits in the African savannah as a herd from dozens to hundreds ones.🐮

Though,it doesn't resemble the cow at all.😳
