Review by Booklist Review
Gr. 3-5. Hickman's elementary discussion of hibernation cites many examples of extreme sleepers to show the wide variations in length and degree of both true hibernation and related states, such as daily torpor and estivation. The author presents reasonably specific information about metabolic changes and related topics with engaging clarity (Painted turtle hatchlings, or babies, can survive temperatures as low as -4\xfb C (25\xfb F). Over half of their body water turns to ice, their heart stops and their blood stops flowing ), and Stephens' carefully detailed painted reptiles, birds, amphibians, and mammals--small and large, most posed in natural settings--add plenty of visual appeal. Several easy science activities complete the nice package. --John Peters Copyright 2005 Booklist

Review by School Library Journal Review
Gr 3-5-The subtitle notwithstanding, Hickman focuses on hibernation, covering true hibernators, deep sleepers, and estivators. She explains why animals use this adaptation, how different species prepare for hibernating and its dangers, and how they awaken in the spring. Sidebars with the heading "If you were a-" and lists of bulleted facts lend variety to the text. Simple experiments that reinforce the information are included. Readers will enjoy the ease of the read and the peaceful, earth-tone watercolor illustrations with the animals labeled. A pleasant addition for animal lovers.-Sandra Welzenbach, Villarreal Elementary School, San Antonio, TX (c) Copyright 2010. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc.

Review by Horn Book Review
Hickman explains the mechanism of slowing animal metabolism related to seasonal weather changes and details variations for many species in clear language. Illustrations of animals are realistically and intimately portrayed in phases of hibernation or aestivation, with revealing cross sections of burrows showing curled up, torpid inhabitants. Simple experiments demonstrate the underlying principles of energy conservation for these ""extreme sleepers."" Glos., ind. (c) Copyright 2010.
