The Titanic, long remembered for its tragic sinking, has transformed into an underwater laboratory, with unique biological and chemical processes actively degrading the wreck. Microbes, including iron-eating bacteria, play a pivotal role in the ship's slow decay, while a new ecosystem of marine life has taken root on the Titanic’s remains. As the wreck continues to disintegrate, it offers researchers invaluable insights into life at the deepest parts of our oceans and the resilience of nature in extreme environments.
