how long can sharks live

Most sharks live around 20–30 years, but some species can reach 100+ years, and Greenland sharks may exceed 250–500 years, making them the longest‑lived vertebrates known.

Quick Scoop: How long can sharks live?

• Most shark species have a typical lifespan of about 20–30 years in the wild.

• Some well‑known sharks (like great whites, tiger sharks, hammerheads) can reach roughly 40–50 years or more, depending on the species and environment.

• A few species are true “ocean elders”: spiny dogfish, whale sharks, and especially Greenland sharks can live over 100 years, with Greenland sharks estimated at at least 250 years and possibly past 500.

Species examples

• Greenland shark: Longest‑lived known vertebrate; age estimates for a large female ranged from about 272 to over 500 years.

• Whale shark: Giant filter‑feeder that may live 70–100+ years.

• Spiny dogfish: Small shark that can reach more than 100 years in some studies.

• Great white, tiger, hammerhead: Common estimates place many individuals in the several‑decade range, roughly up to 40–50 years or a bit more.

Why their lifespans vary

• Different species evolve different growth rates and ages at maturity; slow‑growing, late‑maturing sharks (like Greenland sharks) tend to live much longer.

• Environment matters: wild sharks often live longer than those in captivity, where stress, limited space, and diet differences can shorten lifespans.

• Human impacts (fishing, pollution, habitat loss) can prevent many sharks from ever reaching their natural maximum age.

Big picture

• If you’re wondering “how long can sharks live” in general:
  • Common range: 20–30 years.

* Long‑lived group: 50–100+ years (tiger, thresher, whale, spiny dogfish).

* Extreme record holder: Greenland shark at 250–500+ years.
