National Geographic Kids Sharks!

National Geographic Kids Sharks! It's fast. It's silent. It has five rows of deadly teeth. Smack! Meet the shark! The fish that ruled the deep sea long before dinosaurs roamed the earth! This fish's skeleton is not bone, but soft cartilage, which allows it to glide, turn, and maneuver before its prey can say "swallowed!". It can smell just one drop of blood out of 25 million drops of water in the ocean. It can sense the electricity its prey emits. It loses and replaces more than 10,000 teeth throughout its life. To see all this and more, don't miss this book. Age Group: 6+
