Query: A classic for young and old

When I was a kid my uncle gave me a copy of this book and it opened up a world which still intrigues me...reptiles and amphibians. Even today I consult the book for info on some lizzard I don't recognize or to see if salamanders actually spend a lot of time out of water. In fact, I'm sharing it with my own nephew now--age 11--who's discovering this new world of life for himself. This book is well-presented and easy-to-use, as well as full of great illustrations that alone make it worth reading through. Profiles of each reptile and amphibian are thorough withough being overwhelmingly scientific. A timeless classic for young or old...one to share over the generations.
