Animals face a lot of danger in their natural world. Some animals make a tasty meal for larger animals. Other animals face danger from their own species! But many of these animals have ways to defend themselves. Animals like puffer fish inflate their spiky bodies so that predators can't take a bite out of them. Tarantulas shoot arrow-like hairs out of their bodies that itch and burn the skin of would-be predators! Throughout this book, readers will explore the many defensive measures animals have to keep themselves safe in the wild.
