"This fascinating series takes a very simple look at animal classifications, with each book focussing on a different group of animal. This book is about invertebrates: what they do, how they behave, and how these characteristics are different from other groups of animals. Beautifully illustrated with colorful photographs, the book shows many examples of different types of invertebrates in their natural environment."-- Provided by publisher.
