Bests & Worsts Reviews from Amazon

I bought this to read to my kids because of glowing reviews, and it is a very nicely illustrated book indeed, but I found the content annoyingly lacking. On the elephant page, for example, it depicts two types of elephants in the pictures. One of them is the Asian elephant and this is described in the legend at the bottom. The other one (I assume is the African Elephant) is just ignored...no label or description. And while I know that no book short of an animal encyclopedia can list all members of a group, this book is ridiculously lacking in content. The "Cats" page for example, only has TWO cats: a leopard and a lion! This is missing major, significant members of the groups such as tiger, jaguar, etc... The "Bats" section, however, has 5 different types of bats illustrated and discussed. "Hoofed mammals" for example has only 5 animals - rhino, hippo, giraffe, muntjac deer, and gerenuk...yet the turtle page has 6 different types or turtle. There are so many favorite animals missing in here...I don't get it. The organization is strange too.. sometimes there are pictures of full animals, and sometimes there are just skeleton views or lifecycle views. The "Crocodiles and Alligators" page has only one picture of a croc/alligator, - but it is just the skeleton. I'd rather see a real illustration of each and have the differences pointed out.
