Scientists from Oceanographic institution woods hole revealed that white sharks Carcharodon carcharias can live much more than was thought to this day. The work published in the journal PLoS ONE, short of it can be found on the website of the University. The study was conducted in the tissues white shark collected from 1967 to 2010, the National Agency for fisheries of the United States (NMFS). It turns out that between 8 studied individuals of the age of the oldest is 73 years for males and 40 years for females. Earlier the age limit white shark was estimated only at 22-23. To execute the opening managed using the newest method of Dating, which previously for the study of fish is not running. The method created Christy Spelling of the Karolinska University in Sweden, involves a test of fabrics for isotopes of carbon and measuring the proportion of carbon-14. The concentration of this isotope in the atmosphere has increased dramatically since the start of nuclear tests in the 50-ies of the last century, and later, after the ban tests in 1963, began to fall. Assessing the carbon-14 in different layers of the vertebrae white sharks, scientists could estimate their age. Earlier in order to achieve the desired result was applied counting "annual rings" on the otoliths in the inner ear of fish, but the omission of this method, as demonstrated by the authors, increases significantly with increasing age of the animals. Maximum duration of life traditionally positively correlated with body size: larger than the animal, the more its lifetime. The age limit of the mouse, for example, is 4 years , marmosets 15 years, horse - 57 years, the elephant - 65 years, China - 211 years. This rule, however, there are many significant exceptions. For example, the naked mole rat under similar to mouse volume lives up to 30 years and more. As recently showed biologists, mole rat has a large number of devices such longevity. It ribosomes rather mouse synthesize proteins, and cell division is more tightly controlled, and therefore, I think scientists, the diggers are still not fixed any of the 1-St case of cancer.
