Holland’s latest in the Animal Anatomy and Adaptations series looks at how animals use their noses.
Noses in the animal kingdom are used for more than just smelling and breathing: They are also useful for finding food and mates, avoiding predators, and navigating. A star-nosed mole wiggles the feelers on its nose to locate earthworms underground; a frog can find its home by smell; and a snake collects particles on its tongue and uses the Jacobson’s organ on the roof of its mouth to identify the smells. A wide range of animals is presented here, not all of them with true noses, which the author points out. For instance, birds breathe and smell through nostrils just above their beaks (different species’ senses of smell vary), and insects breathe through spiricles and smell with antennae. Some facts will amaze: Polar bears can smell seals through 3 feet of ice, and beavers’ noses close when underwater. Backmatter includes an explanation of the sense of smell (written at a significantly higher reading level than the primary text), more fun facts, and two matching/identify activities. As with Holland’s previous examinations of animals’ parts, the close-up photos are the main attraction. Vocabulary is defined in the text, which is mainly written for younger readers, with questions to get them engaged, shorter sentences, and simple vocabulary (“peeing and pooping”).
Another solid addition to Holland’s series. (Nonfiction. 3-9)
