Conservation Collection's Critically Endangered books are a children's non-fiction series featuring an A to Z listing of critically endangered and endangered animals currently listed by the International Union for Conservation of Nature's Red List of Threatened Species. The books feature the common and scientific names of each species, where they are found, how many may be left in the world, full-colour illustrations and fun facts about each animal.

The fourth and final book in this series, Conservation Collection's Critically Endangered: Invertebrates, highlights for young readers the often-forgotten species of the world. While not as cuddly as our mammals, these invertebrates dazzle with colour and their adaptations against the threats they face in the wild, and this book brings awareness to their plight and aims to inspire the next generation of entomologists, invertebrate researchers and conservationists.

Travel across continents, from the forests to the ocean, to learn about the many threatened invertebrates around the world, and why we should care for all endangered species and their habitats.

With much dedication and research undertaken for this A to Z book, Conservation Collection's Critically Endangered: Invertebrates hopes to present to young readers the importance of conserving and preserving our environment and the wildlife around us.
