How Animals Smell (Science of Senses)

From sniffing out a meal to finding a mate, species throughout the animal kingdom use their sense of smell every day. While most animals use their noses to smell, such as cats, dogs, and humans, others use different parts of their bodies. For example, bees use their antennae, snakes use their tongues, and butterflies use their legs. A good sense of smell can allow animals to survive in dark, underground habitats. It can help others locate food sources in the vast oceans or the driest of deserts. In this book, readers can find out about how animals' and people's senses of smell work and why this sense is essential for most creatures' everyday lives.
