Photographs and text from the movie. Easier to pick up and read no matter where you are. After reading this highly-photographic book, you will definitely know more about the platypus than anybody you know, unless you know me/Grant. I’ve read three books on the beast, and only two of them were children’s books.
And as a bonus, there are a few pages on the echidna, the closest living relative to the platypus. Echidnas are better than most animals and, that being the case, are worth looking into; but don’t let anybody tell you they’re as good as platypuses.
