It was estimated that lobsters can live up to 70 years. At the same time, it is difficult to determine the true age. Life expectancy is estimated by size and other indirect indicators. As a result of the research, it was found that these arthropods do not lose their childbearing functions with age. On the contrary, the older they are, the more prolific.
This phenomenon is associated with the characteristics of chromosomes that have telomeres at the ends of DNA sequences. But in most vertebrates such restorative enzymes are absent. However, it should be noted that up to 15% of lobsters die during moulting from exhaustion. The survivors grow all their lives and, thanks to their longevity, reach impressive proportions. The exoskeleton begins to collapse, which leads to death.
It is illegal to lower live animals into boiling water. For such actions in Italy, a fine of 500 euros is provided, as lobsters suffer and die within 3 minutes. The best option is killing by electric current. For this purpose, there is a special device with a voltage of 110 volts and a current with an electric discharge of 5 amperes. In this case, lobsters die within 0.3 seconds.
