Find out what sharks are really like in this fun, informative picture book, part of the Nature Storybooks series. The last word you want to hear when you're swimming in the warm blue sea is 'Shark!' But most real sharks are not what you might expect. Some are no bigger than a chocolate bar, some have built-in fairy lights and most wouldn't go near a human, even if you were wearing a sign saying 'dinner'! So if you think all sharks are giant, man-eating killers, you're in for a big surprise.
