What happens when a jumping spider sees an insect that it wants to eat? First, the spider quietly creeps near it—like a cat. Then it leaps through the air and pounces on the victim. Jumping spiders can leap up to 40 times the length of their bodies. If people could do that, they would be able to jump over six school buses parked end to end! These are just some of the surprising facts that young readers will discover as they explore the unusual world of these hairy spiders. Large, eye-popping photographs and fascinating, grade-appropriate text will engage emergent and early readers as they learn about the natural habitat, diet, physical characteristics, and behavior of this unique invertebrate.
