Which animals have multiple sets of teeth?

sahar, The reason these unrelated species must have multiple molars, is because they all eat a tough type of food that is hard on their teeth and they live a relatively long life. If their teeth were worn out when they were young, they would die of starvation. On a similar, but unhappy note. Walruses use their tusks as a defense, but also to keep their breathing holes open. Once they wear their tusks down, that's it, they don't get new ones. They don't survive for very long without usable tusks.🥲

Surely if all three answers are correct it's impossible to pick a wrong answer?

interesting but these species seem unrelated to each other elephants kangaroos manatees

How useful it would be to have this "skill" - I had 2 upper molars out recently and they are very much missed!

Yes We can’t leave out Sharks which has rows of new teeth that grows and moves forward to replace the damaged ones in the front. ! ! !
