We LOVE this book. For a start, it is MASSIVE in size - much larger than A4 - and the illustrations are beautiful. It's a great learning tool for children to get to see animals and birds of the world, and their attention can be captivated for many hours as they explore horned beasts, freshwater fish, creatures with spots and stripes, animals that live in hot climates...the list goes on and on!
Children learn what different animals look like, how they live, what they're called - and the little extra "task" of finding the chameleon on each page is also a good way of maintaining a child's interest. I'd say this was a book for all ages; from the very young (one and a half) to the somewhat older (I've seen a thirteen year old captivated by it when he thought he wasn't being watched).
It was given to us as a birthday present and I have gone on to order it for other people as a result of its generic appeal. Did I mention that adults like it too and it can be used as a good animal reference tool?
Well worth every penny spent!
