Here is ur Answer mate..
There are different types of sharks found in the earth & their ages depends on their type.
For example, the spiny dogfish has one of the longest lifespans on Earth with more than 100 years, while the blue shark in the wild has an average life expectancy of 15-16 years. Nevertheless, as we mention before, blue shark lifespan lowers down to 8 years when held in captivity, perhaps as a result of the inactivity inherent to captivity.
The oldest shark teeth are from the Devonian Period, about 400 million years old, found in Europe.
