What mammal has the strongest teeth?

It's hard to definitively say which mammal has the *strongest* teeth, as "strength" can be measured in different ways. However, there are a few contenders based on different criteria:

For sheer biting force:

* Hippopotamus: The hippopotamus has the strongest bite force of any land mammal, estimated at over 1,800 pounds per square inch (psi). They use their powerful jaws to crush bones and vegetation.

* American alligator: While not a mammal, alligators have an incredible bite force of around 2,125 psi, making them a contender for the strongest bite in the animal kingdom.

For crushing strength:

* Hyrax: These small, rabbit-like mammals have surprisingly strong teeth, built for grinding tough vegetation. Their molars are incredibly durable and can withstand immense pressure.

* Beavers: Beavers are known for their ability to gnaw through wood, and their teeth are exceptionally strong and sharp. They use their teeth to cut down trees and build dams.

For tearing strength:

* Lions: Lions have powerful, sharp canine teeth that are designed for tearing flesh. Their bite force is around 650 psi, which is enough to crush bones.

Ultimately, the "strongest" teeth depend on how you define strength. If it's about sheer power, the hippopotamus wins. If it's about crushing ability, the hyrax and beaver are strong contenders. And if it's about tearing, the lion takes the crown.
