Animal NapsHardcover, 1 July 2011

Fun, full-color photographs illustrate the sleeping habits and locales of more than two dozen animals. Leopards, koalas, and some types of monkeys sleep high in trees, while seals and tortoises doze on sandy beaches in the sunshine. Kangaroos cover their eyes with their paws, and some types of bats pull their wings over their bodies like bedspreads!
