I came across this oversized book when I was researching children’s books for Christmas presents. This is not a children’s book. After looking at this book, I would have to say, this book is geared for older individuals and I wouldn’t buy it unless my child was very interested in them. Why? Because this book tends to read like a science book. It uses larger vocabulary and uses scientific terms for the animals, to me, it just is not a fun book to read for younger children or for them to look at. You really need to know something of what you are reading to understand this book. The book is broken down into invertebrates, fish, amphibians, reptiles, birds, and mammals. An example of the words that I found that might be difficult are: formidable dexterity, unprecedented, dermal denticles and dynamic lift. Don’t get me wrong the text has great information but it is geared for older individuals or individuals who are diverse in the language of the species. On each two-page spread of this oversized book, there is an oversized illustration of the species and printed text pertaining to that illustration. There are also key details about that species in a little subsection after the text. I found the book rather overwhelming after a while and had to take a break. The book is printed on hard stock off-white paper and the illustrations were interesting. I found it a good book to thumb through, overwhelming for me to read but I think for others, I can see that it would have lots of great material to read.
