5 Fun Facts about Polar Bears, Penguins, and Other Mysterious Animals of the Extreme Cold

Enslow author Anna Maria Rodriguez's new book, Polar Bears, Penguins, and Other Mysterious Animals of the Extreme Cold gives us a glimpse into the world of the unusual animals that live near the north and south poles. Since Polar Bears, Penguins, and Other Mysterious Animals of the Extreme Cold will be released soon, I'd like to share a 5 interesting facts from the book:

1. Polar bears spend so much time swimming and on ice floes that they are actually considered marine mammals. If you translate their scientific name, Ursus maritimus, you'll see that it means "Sea Bear".

2. The Antarctic cod has special proteins, called peptides, that prevent it from freezing.

3. Adult male polar bears will usually not hibernate during the winter.

4. Scientists have located major emperor penguin colonies by taking satelite images of Antarctica and looking for areas stained by penguin guano.

5. Polar bears will sometimes show signs of frustration when they lose a seal that they have been hunting.
