A Polar Bear Can Swim: What Animals Can and Cannot Do

(3) K-3 Science Easy-to-Read series. Illustrated by Emily Bolam. A polar bear can swim, dive, and sleep curled up, but he can't sleep upside-down; a bat can sleep upside-down, but he can't fly backwards; a hummingbird can fly backwards, though. This series of simple animal facts, illustrated with amiable-looking creatures (on unfortunately thin paper) will prove an entertaining primer for budding naturalists.
