Amazon.com description: Product Description: In this latest installment of the Cat in the Hat's Learning Library, the Cat introduces beginning readers to all kinds of sharks! From the smallest (the dwarf lantern) to the largest (the whale shark), the most notorius (the great white) to the most obscure (the goblin), the Cat explains why sharks have lots of teeth but no bones; how their tough skin helps them swim fast and stay clean (inspiring scientists--and bathing suit manufacturers!); how pores along the sides of their bodies help them sense prey; that they have more to fear from us than we do from them, and much, much more! Perfect for shark and Cat (in the Hat) fanciers, fans of the new PBS Kids preschool science show The Cat in the Hat Knows a Lot About That! will sink their teeth into this new addition to the series!
