A new series of colorful and lighthearted books that compares opposites in the weird and wonderful animal kingdom.

Children are often intrigued by extremes in the world around them and how they compare to each other – the biggest and the smallest, the fastest and the slowest, the smartest and the silliest. These books describe and illustrate animals’ characteristics and compare them to animals with exactly the opposite characteristics. Young readers will learn fascinating facts about dozens of creatures from around the world while having some serious fun.

All of the books include practical notes for parents and teachers about learning activities and games.

Smartest and Silliest features photographs of animals with detailed captions that describe how smart or silly they really are. Some are engaged in activities, and others demonstrate how size affects any number of things – survival, play, appearance and more. Included are sheep that can recognize the faces of as many as 50 other sheep, sponges without brains, purple flatworms that can find their way through mazes (and remember the fastest route) and apes that can saw wood, hammer nails and wash clothes with soap.
