Life in a Frozen World: Wildlife of Antarctica

Gr 3-5–This informative introduction to earth science details how animals live and thrive in Antarctica. Batten presents many fascinating examples of how penguins, seals, and icefish adapt to this challenging climate. Their survival depends on the availability of krill, small shrimplike crustaceans that are a source of food. Krill are uniquely adapted to survive in Antarctica because they can shrink themselves and go without food for long periods of time. Whales, too, have traits that assist their survival. These warm-blooded mammals migrate to other places during the coldest seasons. They have a layer of blubber under their skin that keeps them warm, and they can regulate their body temperature. The text also discusses the consequences of climate change. Topics include how scientists collect ice cores to learn about changing conditions, scientific research under the water, the impact of melting ice on animals, and the melting of ice shelves that surround Antarctica. The text makes a compelling case for understanding and caring about Antarctica. Gonzalez’s illustrations provide an intriguing depiction of the setting.
