The time it takes for a shark use and lose each tooth varies, depending on the species and age. Younger sharks replace their teeth more often. There is also some evidence that sharksâ teeth last significantly longer during colder water temperature in some sharks, a time when they traditionally eat less.

The Titanic was a ship that sank on her maiden voyage from Belfast to New York by colliding with an iceberg in the Atlantic ocean in 1912. Of 2229 passengers and crew, only 713 survived to be rescued by the MV Carpathia, making this the largest loss of life on a passenger vessel at that time.
