From Caldecott Honor?winning author-illustrator Steve Jenkins comes a series of animals with unusual eyes in this eye-catching picture book!
In his eye-popping work of picture book nonfiction, Jenkins explains how for most animals, eyes are the most important source of information about the world in a biological sense.
The simplest eyes?clusters of light-sensitive cells?appeared more than one billion years ago, and provided a big survival advantage to the first creatures that had them. Since then, animals have evolved an amazing variety of eyes, along with often surprising ways to use them.
