The Secret Life of Fish

There are 33,000 species of fish on our planet, and that number is constantly increasing. In context, that is more than all the species of mammals, birds, amphibians and reptiles added together, making fish the most numerous vertebrates on our planet. This book reveals the astonishing truth about our aquatic cousins: how they think and what they know, their experiences and unique behaviours, and the many things we have in common.
