Sir Waddle has counted a great many teeth. He does not recommend it.

Meet a shark that grows new teeth its entire life. A crocodile with one of the strongest bites ever measured. A deep-sea fish whose teeth point backward so dinner can't escape, and a narwhal whose famous "horn" is actually a tooth. From piranhas to hippos, these animals prove that a good set of teeth can be a tool, a weapon, or a truly spectacular smile.

Led by Sir Waddle, a naturalist who studies his subjects from a respectful distance, young readers discover thirty of the toothiest animals on the planet through real science, gentle humor, and stunning vintage natural history illustrations.

"I make a point of approaching from the front and complimenting their smiles." —Sir Waddle

Inside you'll find:

• 30 toothy animals, including the great white shark, saltwater crocodile, Komodo dragon, and vampire bat

• Hands-on "Try It!" activities

Thrilling but never gory, it's perfect for animal-loving kids ages 7–10, reluctant readers, classrooms, and anyone who has ever wondered why sharks never need a dentist.
