Mammal teeth have evolved to do a number of things including grinding, ripping, tearing, etc. And elephants are no exception. African elephants have the largest teeth in the world! An African elephant’s tusks are modified incisors. They can reach up to 465 pounds (for both teeth). We only see about 2/3rds of the actual incisor, the rest of the tooth is hidden by the Elephant’s skull. Walruses are another mammal with exceptionally large teeth.
Fun Fact: Teeth are the hardest part of any mammal, which is why we have such great fossils!
Another contender for the crown of largest teeth may go to the Narwhal Whale. They are found exclusively in the arctic waters of Canada and Greenland. They have one (on occasion two) large incisors that can grow up to 3 meters long, elephants tusks grow up to about the same length. The Narwhal is a very unique and very interesting animal. They are one of two species of whale in the Monodontidae family, where the other is the Beluga. An exclusive and beautiful family.
