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.

Men in third class experienced the largest fatality rate. Only about 20% of men on the ship itself survived, and of the 1,517 fatalities on the ship, 1,347 were men. Most of the crew was also lost during the sinking of the Titanic. Out of the 899 crew members on board, 685 went down with the ship. Titanic survivors were mostly men and women. About 74% of the women survived as did about 52% of the children. All the children from first and second class survived, while most of the loss of child life came from third class. The Titanic had the capacity to hold 32 lifeboats, but this was not mandatory under maritime law of the time.
