Which animals have the strongest bite?

5. Hippopotamus 1,800 PSI (126.5 kg/cm2)

Many people imagine hippos as kind chubsters. In reality, they’re one of the most dangerous animals in Africa, and can be pretty aggressive — their bite can kill a lion or a crocodile. A hippo can crush a watermelon with the same ease as a person crushes a grape in his mouth.
