From the creators of Genius Noses comes an illustrated collection of animal ears and their amazing functions. Early STEM has never been more fun in this fact-filled book featuring everything kids ever wanted to know about animal ears around the world! Ears can do much more than just pick up sound waves. In the animal kingdom, ears are sometimes an animal's strongest asset! For example, a fleeing black-tailed jackrabbit uses the position of its ears to help it confuse its pursuers and get away from danger. Some animals can close their ears to protect their bodies or use them to cool down or stay warm. Whether long, tuft, or goblin, ears can tell a lot about animals and their habits and habitats. Which animal has the longest ears relative to its size? Which animal communicates through surprisingly high-pitched chirping sounds? And which animal can pinpoint the location of its prey using only its ears? Readers will find out all this and much more in this entertaining collection filled with unique and unusual facts.
