How long do Greenland sharks live?
The lifespan of Greenland sharks is generally estimated to be between 50 and 100 years. The longevity of these enormous fish is remarkable given its slow growth and late sexual maturity. The species appears to be relatively long-lived for a shark of its size, possibly because they have a high metabolic rate.
How long do Greenland sharks live in captivity?
Greenland shark lifespan in captivity is often estimated using their age at capture, but this is a problematic method. It is possible for captors to capture a young Greenland shark for the purposes of maintaining a food source. Thus, the apparent age of a captive Greenland shark can be much lower than their actual age.
How long do Greenland sharks live in the ocean?
The longevity of Greenland sharks in the ocean is unknown. However, some shark species live for over 100 years in natural environments. Although Greenland shark species are long-lived in the wild, the species is vulnerable due to overfishing.
How long can Greenland sharks live in captivity?
We don’t know for sure. There are no long-term studies on this species in captivity, so we don’t know how long they can live. However, Greenland sharks can live to around 100 years when in the wild, so it’s not impossible they could live that long in captivity.
How long do Greenland sharks live in the wild?
The exact lifespan of Greenland sharks remains unknown. However, a recent study suggests that the species could live for around 140 years. Researchers collected data on the age of the Greenland sharks that were caught by commercial fisheries and found that the average age of the sharks was 23 years. However, the oldest shark they found was an astonishing 74 years old!
