Crocodile cannot die of old age! They keep eating more and more food as they grow until they finally die of hunger,get diseases or being killed by predator.
Crocodiles have no such thing as old age. A 7-year-old crocodile is as good as a 70-year-old one in terms of agility and other life parameters. Aging has no effect on them. Although they can’t die of natural aging, they also can’t live forever. Nature has a way of killing them. The way they die is out of starvation or if they contract a disease.
They keep growing throughout their lifespan and they require more and more food. So, as they keep getting older they need a lot more food. When that amount of food is unavailable, they die from starvation. That is the reason we don’t see 1000 year old crocodiles that are 50 feet long. Still, see what this hunter shot in Australia in the year 1957 – It was an 8.1 m (28 feet) long crocodile!
Even if making human beings biologically immortal is an extremely controversial area, it doesn’t stop scientists. Scientists love to study organisms that exhibit negligible senescence because they’d love to find out a way to halt the aging process in humans by mimicking their gene structures. Probably, in the near future, we’ll find a way to demonstrate limitless Telomere regenerative capacity like Planarian Flatworms in humans.
