Sharks can live for more than 70 years

Recent research by American scientists shows that white sharks can live more than 70 years, more than three times the highest life recorded so far.

To determine the life of the white shark, scientists used radioactive carbon technology and analyzed the vertebrae of four males and four females living in the northwest Atlantic Ocean.

According to the analysis results, the age of the largest males was determined to be 73, the largest females aged 40, AFP said.

Li Ling Hamady, a member of the research team at Woods Hole Oceanographic Institute, said the results of the study provide new evidence for white shark life as compared to previous studies.

Determining the age of sharks was primarily done by studying the growth of the ear stone (shark's inner ear, made of bone), similar to the pattern on the woody body.

By this method, experts identified two white sharks with the highest life expectancy of 22 and 23 years, discovered in turn in the southwestern Pacific and western Indian Ocean.

White sharks are considered one of the most vulnerable species in the animal world. Determining the lifespan and the development of sharks can help researchers develop ways to preserve this animal in the future.
