001 - Preface

Dive into the fascinating world of invertebrate animals with this enlightening book. While many people picture animals as fish, birds, or mammals, a staggering 90% of animal species on our planet are invertebrates—creatures without backbones. From the deepest oceans to lush rainforests, ice caves, and even your own backyard, invertebrates are everywhere. This captivating journey through Holders work uncovers a diverse array of both familiar and lesser-known invertebrates, tracing their lineage back to the Cambrian period, over 500 million years ago. Join narrator Jefferey Smith as he brings these remarkable creatures to life.
