Why do turtle lives longer?

As a general rule, animals with a high metabolic rate die early, and those that burn energy more slowly plod on for decades. The more active the animal, the higher its metabolic rate, as it has to burn energy to maintain its activity.

Take the shrew: its life is a blur, and few live to be two years old. Likewise hummingbirds.
Giant tortoises on the other hand, which burn energy at a far lower rate, can crawl into an eighteenth decade.

So as they are slow and reduce the expenditure of energy they are able to live longer and stronger. Heard of “live fast, die young”? Well, the opposite is true as well.

one another way can we also its as so they can reproduce more effectively. Long life spans provide an evolutionary advantage for certain types of animals. It makes sense to stick around if you live in an unpredictable or harsh environment where it’s hard to reproduce on a regular basis. (Desert animals, for example, tend to get quite old before they die.) You’d also want to have a long life if you could only give birth infrequently for some other reason, or if you spent a lot of time caring for each of your offspring. 

Every species has its own “life history,” or schedule according to which it passes on its genes to the next generation. Some animals invest their time and energy in having lots of babies while they’re young; others use their resources to live longer. An animal might live fast if there are lots of predators around—if you’re going to die young, you might as well get the baby-making over with as early as possible. (This strategy works only in a predictable environment, where you know there will be enough food around to feed all your babies.) The long-lived animals, on the other hand, have often evolved some way to protect themselves from predators.

That’s why armored beasts—like turtles, armadillos, and beetles—tend to stick around for a while compared to similarly sized animals. Flying animals also seem to have an advantage; bats last much longer than rodents, perhaps because they can escape predators more easily. Very poisonous animals can last a long time, as well—any strong defense against predation will do the trick.

The giant tortoise has an armored shell for protection, but it also has a couple of other features that correlate with long life. As an island species, it has enjoyed natural protection from predators over the course of its history. It’s also very large, and larger animals tend to live longer than small ones. (There are plenty of exceptions to the bigger-lives-longer rule—take the little bat, for example. Large body size also goes along with living on an island.

  • All of these factors interact over the course of an animal’s evolutionary history, so you can’t say one trait causes another. We can’t conclude that a tortoise lives to 255 because it has a shell or because it’s big; nor can we say that the tortoise evolved a shell or its large size because it has such a long life. Other types of animals—especially those with bigger brains—seem to have developed long life spans for different reasons entirely: In general, the more social the animal, the longer it lives. Social insects have more longevity than the lonesome varieties: Some flies last only a couple of days, while a termite queen can survive for 30 years.
  • As i discussed in my previous blog all about antioxidants,that it can eat ups all the free radicals generated during metabolism and enhance the life and prevents from became old; Similarly here turtle with slowest metabolism  rate so it create less free radical and ultimately life is increases.
  • One another thing is here is about heart life,as it beats faster rate its validity is decrease;slower as it less wear and tear,and life is increases. Actually turtle travels in water with the speed of 32 Km/Hr which is not slow, and its same as if someone calls us to run under water,as we can’t walk faster under water how can turtle walk faster over the soil.
  • Its also similar to the old Indian monks slows down their metabolism while meditate and decrease all energy consumption and reduce the production of free radical and survive for more than above expected years.

    In psychologically all that are similar “if you try to live all thing at same time your life,  life gets reduced but if you do it slowly life increases, but in both the cases you have to pass same number of moments whatever may its speed”.
