Understanding the lifespan and aging process of marine species has long been a challenge for researchers. Unlike mammals, which have bones that contain growth rings similar to tree rings, sharks possess a cartilaginous skeleton that does not retain clear aging markers. However, a breakthrough in marine science has emerged through the study of the great white shark tooth, providing valuable insights into the age and growth patterns of this apex predator. By analyzing the unique structure of shark teeth, researchers have uncovered critical data that reshape previous assumptions about their longevity and life history.
