Over all it is a good book for however it lacks editing and continuity. Their seas and ocean page is lacking. I know this is a bit silly but their examples are crab, sea turtle, porcupine fish, jellyfish, dolphin, fish, sea lion, starfish, and whale. They have terrapin for a type of turtle which means they could have been more specific instead of saying "fish" repeatedly. Then again, they have penguins in two sections in a total of twelve pages.
