About longevity of animals there is a set of stories and legends which are often strongly exaggerated. Among heavenly, terrestrial and sea inhabitants there are champions on life expectancy, but the mammal living most longer nevertheless exists.
Statistics of long-livers of faunaOne of the most long-living overland animals by right is the monkey chimpanzee living up to 60-70 years. Slightly less the horse who at ideal leaving lives up to 50 and more years can live. Hippopotamuses live about 41 years, rhinoceroses – 40, bears – 34, ordinary monkeys – more than 20 years, cats – 23 years, dogs – 22 years.
This statistics was not exposed to averaging and concerns certain animals, but not features of a concrete look.
The following regularity is characteristic of mammals: the they are larger, the longer duration of their life. So, the two-ton elephant with very high probability will live to 70 years – knowing the average weight of a mammal, it is possible to predict his maximum age precisely. However and in this rule there are exceptions as the person in this situation would have to live no more than 30 years. Here already other law works – at identical body weight there live longer those mammals who have a brain size more. In this case slow aging is explained by the fact that the large brain operates all vital signs of the owner with higher quality.
Unconditional championsAmong overland mammals the elephant which average life expectancy usually makes from 60 to 90 years repeatedly admitted to the most long-living. The truth only some representatives of this look differing in enviable health and amazing thickness of a skin live up to respectable 90-year age.
Scientists consider that elephants are obliged by such long life to the vegetable food and very measured, slow existence.
What mammal is recognized as the most long-living on Earth? The whale who can live till an extreme 130-year old age is considered the champion in this area Greenland, or polar. Whales are the largest animals in the world – they can grow up in length up to 35 meters and have weight in 150 tons. Newborns of the kityat reach 7 meters in length and for one feeding consume about 7 buckets of milk. However, if to consider not only mammals, then the oldest long-liver is the ordinary Mauritian turtle who lived 152 years and, according to some biologists, quite has every chance "to doskripet" quietly about record 200 years. At the same time her relative, the royal turtle living in America can live up to 123 years.
