The Top 7 Animals with the Largest Teeth: The Size of an Animal’s Bite

Animals with the Largest Teeth

Teeth size is often directly related to an animal’s diet and feeding habits. Animals that are carnivores or rely on tough plant materials tend to have larger teeth to help them kill prey or grind plant matter.

In the animal kingdom, size definitely matters when it comes to teeth. In this blog article, we will be sharing about 7 top animals with the largest teeth.

Ranking the Top 7 Animals with the Largest Teeth

7. Giant Armadillo

Giant Armadillo

In fourth place are giant armadillos, which live in South America. They use their sizable teeth to crack into ant and termite nests in search of food. Their molars can reach lengths of 1.5 inches (4 cm) to help pulverize insects.

For their body size, giant armadillos have the largest teeth-to-head ratio within the animal kingdom. Still, giant armadillo teeth have relatively weak enamel and must regrow quickly. In fact, they can go through 8,000 teeth over their lifetime!

6. Walrus: Mustache Masters


Forget Hollywood heartthrobs, the walrus rocks the ultimate mustache with its elongated upper canine teeth called tusks. These ivory beauties can reach up to 3 feet in length and weigh over 70 pounds, serving as multi-purpose tools.

Walruses use their tusks for hauling themselves onto ice, fighting rivals, and even digging for clams and other tasty treats. These impressive chompers are a testament to the walrus’s adaptation to the harsh Arctic environment.

5. Saber-Toothed Salmon

One ocean-dweller makes its way onto our list – the saber-toothed salmon. Occurring in the Pacific and Arctic Oceans, this carnivorous salmon grows elongated and spear-like teeth reaching lengths of around 1 inch (2.5 cm). Their fearsome fangs help them lock onto prey like smaller fish.

Researchers believe fangs also play a role in mating rituals. Truly, no other salmon or trout species compares with the awesome dentition of the saber-tooth.

4. Hippopotamus


Kicking off our list is the hippopotamus. These large semi-aquatic mammals inhabit rivers and lakes across sub-Saharan Africa. Hippos feed primarily on grass and use their huge teeth to grind up plant matter before swallowing. Their tusks and large canine teeth can reach lengths over 20 inches (50 cm).

Hippo teeth continually grow to account for wear and tear from their abrasive diet. Particularly large hippo teeth can weigh over 6.5 pounds (3 kg) each! Still, their teeth are relatively small considering the hippo’s enormous 3,000+ pound (1,400+ kg) body size.

3. African Elephant

Move over, vampires, because the real tuskers reside in the savannas of Africa. The African elephant boasts two colossal incisors called tusks, which can reach up to 8 feet in length and weigh over 200 pounds!

These ivory giants are not technically teeth, but modified incisors composed of a unique material called dentin. Though majestic, their allure has fueled a devastating ivory trade, making elephant conservation a critical issue.

2. Narwhal: The Unicorn of the Sea

Myths and legends speak of unicorns, but the ocean offers a living, breathing version in the form of the narwhal. This Arctic wonder sports a single, long, spiraling tusk protruding from its upper jaw.

This “unicorn horn,” actually a modified upper canine tooth, can grow up to 10 feet long, making it the longest tooth of any mammal relative to its body size. While its purpose remains debated, scientists believe it may play a role in sensory perception, social interactions, and even icebreaking.

1. Sperm Whale

And finally, the largest teeth of any known animal belong to the sperm whale. Growing up 50 feet (15 m) long on average, sperm whales dive deep in search of squid, sharks, and other prey. To effectively capture and consume large marine animals, they wield massive teeth that can exceed 12 inches (30 cm) in length and weigh 2.4 pounds (1.1 kg) each!

Their conical lower teeth fit into sockets along the jawline. Sperm whales usually possess about 20-26 functional teeth per jaw that interlock to seize slippery prey. Lifespan tooth replacement helps accommodate their vigorous feeding strategy in the deep sea.

Beyond Size

While size is impressive, the animal kingdom showcases incredible dental diversity. Here are some additional noteworthy mentions:

  • Great White Shark: With over 3,000 serrated teeth constantly replenishing, this ocean predator reigns supreme in tooth count.
  • Viperfish: This deep-sea dweller boasts fangs so long they extend beyond its snout, a gruesome adaptation for catching elusive prey.
  • Giant Isopod: Imagine a cockroach the size of a football with teeth capable of crushing a crab’s shell. That’s the reality of the giant isopod, proving size isn’t everything when it comes to fearsome chompers.

Fun Facts about Animal Teeth:

  • Snails hold the record for most teeth, with some species boasting over 20,000!
  • Dolphins wear “dentures” of sorts, with new teeth pushing older ones out as they age.
  • Rodents never stop growing their front teeth, which is why they constantly gnaw to keep them in check.

From river monsters like hippos to marine giants of both modern and ancient oceans, nature has crafted some mightily toothy beasts. When it comes to sheer size and scale, sperm whales possess the largest teeth on record. This no doubt aids their role as apex predators of ocean depths too extreme for other creatures.

Beyond food consumption alone, animals often utilize their teeth for defensive or mating purposes across many unique habitats. One thing is certain – large teeth allow various mammal and fish species to exploit ecological niches other animals cannot. So next time you grin, remember – you pale in comparison with these magnificent beasts of nature flaunting their dental dexterity!
