Some fish can tell large numbers from small ones, hyenas can count, and chimpanzees can use Arabic numerals! Get to know these extraordinary animals and more in this fascinating second book in the Extraordinary Animals series. Each chapter wraps up with an interview with a researcher and a hands-on activity for readers to challenge their own maths skills. Illustrations brimming with personality, along with colourful photos, sidebars and splashy facts ensure that this fact-filled book is entertaining and accessible. A bibliography as well as an “Add to Your Knowledge” section at the back encourage more discovery.
