Jumping spiders can jump up to 40 times their own body lengths! These large-eyed, furry spiders are often kept as pets by people, and can be trained to jump from finger to finger on their owners hand. However appealing-looking they might be, jumping spiders are also ruthless carnivores, as an incredible photograph of their jaws and fangs in this book shows. This book will teach readers about these amazingly athletic spiders and the ways in which they live and hunt.
