Did you know that sharks are among the oldest creatures on earth? They swam through the primordial oceans long before there were dinosaurs. Many legends surround these animals with their fearsome sharp teeth. But how dangerous are sharks really? In this book, you will not only find out how sharks were able to survive so many other animals and how many different species we know today, but also a lot about their very special teeth, their peculiar lateral line organ and excellent sense of smell. However, many sharks have hardly been researched to this day - their habitats are too deep in the sea for us humans to reach. This book is the starting point for so much more to explore about sharks.
