Humans have many ways to defend and protect themselves. Medieval knights used swords and shields. What do animals have? Some animals have adapted to their surroundings by growing scales and scutes. Most people know that fish have scales, but animals such as snakes and sharks have scales, too. Scutes are like one big scale, almost like a shield, that protects the animals such as turtles, crocodiles, and pangolins. This book explores the many animals with scales and scutes, and highlights how these adaptations have developed over time.
