Gina of Goodreads wrote: A bit torn on this rating. On one hand, it is packed with interesting information and 99 percent of the illustrations are great. On the other, the backgrounds sometimes make the text hard to read, some of the info is a tad out of date (which I know can't be helped), and no one needed the imagery of an Ocean Sunfish twirling a Portuguese Man O'War's tentacles like spaghetti.
