The secrets of long life? : Study reveals some species don’t seem to age at all

Ever wondered about the secret to a long life? Perhaps understanding the lifespans of other animals with backbones (or “vertebrates”) might help us unlock this mystery.

You’ve probably heard turtles live a long (and slow) life. At 190 years, Jonathan the Seychelles giant tortoise might be the oldest land animal alive. But why do some animals live longer than others?

We used long-term data from 77 different species of reptiles and amphibians – all cold-blooded animals. Our work is a collaboration between more than 100 scientists with up to 60 years of data on animals that were caught, marked, released and re-caught.

These data were then compared to existing information on warm-blooded animals, and several different ideas about ageing emerged.

Research published today by myself and colleagues in the journal Science investigates the various factors that may affect longevity (lifespan) and ageing in reptiles and amphibians.

They should study the life of the Greenland sharks. They keep the key & secret of long life. The Greenland shark has the longest known lifespan of all vertebrate species (estimated to be between 250 and 500 years). There are claims about captured specimens which are around 600 years old.

Greenland shark found in Cornwall could be 500 years old

An extremely rare Greenland shark, which was found in Cornwall yesterday, could have lived for hundreds of years.

The fascinating animal was first spotted on a beach at Newlyn Harbour near Penzance on Sunday before the tide came in and washed it back out into sea. It was an incredible find for wildlife lovers, as Greenland sharks are very rare. In fact, it was only the second time one has been located in UK waters.
