Did You Know Piranha Can Bite With Tremendous Force? | Wildlife

The shape of a piranha's tooth is strikingly similar to the shape of a blade, which is perfect for carnivores like them. The tooth enamel structure is similar to that of sharks, which is why their teeth are so durable. Piranhas often lose their teeth throughout their lives. Sharks replace their teeth one at a time, but piranhas replace their teeth in quarters multiple times throughout their lifespan, which can last up to 8 years in captivity. Piranhas that are missing half the teeth of the lower jaw are not something out of the ordinary.
