Among the largest mammal species worldwide, whales are also the ones
that can live the longest. Many studies have been carried out by
researchers and have determined that, while some have a life expectancy between 80 and 90 years, some specimens can live up to 100 and more.
Their longevity depends on many factors. Studies have been very
difficult to carry out, however, with some data and estimates, marine
biologists have been able to determine whale lifespan with a pretty good
degree of accuracy, for each species in particular.
