The whole premise behind this book is completely lame.  It doesn’t describe any of the adaptations these animals make that allow them to survive extreme cold.  It’s simply an illustrated list of animals who do live in cold climates.  But the format in which it is presented borders on false: each page simply states an animal that can survive at a given temperature and then asks the question whether any animal exists in colder climate (the first page starts with an Arctic bumblebee that survives 40 degrees — even us wimpy humans in our mild Pacific Northwest climate survive colder than that every winter).  As you turn the page, the pictured thermometer drops a few more degrees, and another animal is declared to survive even that temperature.  The polar bear is described as surviving -34 degrees — you’re telling me if the temperature drops to -35 degrees all the polar bears drop down dead?  Given that many of the animals listed live in the same geographical areas, I’m guessing they must survive together.  After the last animal listed (the Siberian husky at -75 degrees), the repeated question as to whether any animal can exist in a colder climate is answered with, “Perhaps. Who knows what could exist in colder climates?”  I’m thinking man’s study of the temperature ranges in different parts of our world, and the animals who live in those regions is pretty vast, do data probably does exist as to what is the coldest part of the planet and what kind of animals live there.  The whole thing is just bad science, badly written.  The illustrations are nice, but they’re not enough to rescue the poor text. Don’t buy it.
