20 to 30 years.
Most sharks live 20 to 30 years in the wild, but some species can live far longer. At the extreme end of the longevity scale are Greenland sharks, which can live at least 272 years, making them the longest-lived vertebrates (backboned animals) in existence.
How long do sharks tend to live?

How long do sharks live in the wild vs captivity?

How long can a shark live in captivity?
Species appropriate to home aquaria represent considerable spatial and financial investments as they generally approach adult lengths of 3 feet and can live up to 25 years. Sharks must be housed in aquaria at or exceeding 180 gallons in volume, with more active species requiring more space.
Do sharks go to sleep?
Whatever method they use to breathe, sharks are able to engage in periods of deep rest while still but do not fall asleep in the traditional sense. Lacking eyelids, their eyes remain perpetually open, and their pupils still monitor the motion of creatures swimming around them.

How long did Megalodon live?
It was 46 years old when it died. They estimate its length to have been 30 feet. Some megalodons are estimated to have been much larger―as long as 50 feet. Using the data from this study, together with previous research, the researchers concluded that the potential lifespan of megalodons was 88-100 years.
Why can’t sharks be in aquariums?
Sharks are nomadic animals, so keeping them in confined spaces does not bode well. Many of them aggressively hit aquarium tanks, trying to break through the walls or glass, even at the expense of their own well-being. They can hurt themselves so badly that many of them die from their own injuries.
