This week we venture into the fascinating world of a very well-known sea dweller: the shark. With an estimated age of more than 300 million years, the shark is considered to be one of the oldest surviving species. There are hundreds of different types of sharks, from the small tail shark measuring only 20cm up to the 13m long whale shark, the largest fish in the world. ![Discover pictures and videos of Sharks here!]()
Beside pointed fins (which actually not all species have) probably the most famous of many others features is the so-called revolver dentition, which ensures that a lost tooth is replaced in a few days.
