Many animals use their adaptations to defend themselves against predators, attack their prey, and compete for mates. Fangs and claws help animals do all of these things. However, these adaptations didn't appear overnight, they took millions of years. Animals such as tigers have both fangs and claws and use them to catch their prey. The information in this book explains how these adaptations appeared over time and how they benefit animals. Scientific discoveries are also highlighted to provide additional insight. Dazzling photographs of fangs and claws bring the subject matter into vivid focus.
