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.

Titanic artifacts reveal gruesome discovery of tragic ship's last lifeboat. The Titanic lifeboat recovered by crewmembers from RMS Oceanic (Henry Aldridge & Son). Photos and a handwritten note detailing the grisly discovery of Titanicâs last lifeboat will be auctioned in the U.K. later this week. The three photos were taken on May 13, 1912, almost a month after Titanicâs sinking, and show crewmembers from RMS Oceanic attempting to recover one of the doomed linerâs lifeboats. Inside the lifeboat, thought to be the last to leave the sinking ship, were the decomposing bodies of three Titanic passengers.
