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 The World of Sharks, you will not only find out how sharks were able to survive so many other animals and how many different spe- cies 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.
