Sharks are huge, torpedo-shaped animals that have prowled the Earth's oceans for over 100 million years. Great whites can sense tiny amounts of blood in the water up to 3 miles away and have over 300 teeth to chomp with. Hammerheads swim in tropical waters looking to pin stingrays against the rocks with their wide heads. Tiger sharks, with their ferocious-looking stripes, can grow up to 25 feet long. "The National Geographic Kids Everything Series" shows kids these sharks and much more. National Geographic explorers take readers behind-the-scenes into the watery world of sharks and tell their extraordinary tales about their interactions with these creatures. Filled with fun facts and action-packed photographs, this book lets kids see below the surface and into the lives of sharks.
