Whales are a group of creatures that we are familiar with, and most of them live in the ocean. They are at the top of the marine biological chain, and their life span is longer than that of most fish in the ocean, which can live for decades or even 100 years. Specifically, their life span is not necessarily, and there are many factors affecting it. For example, species is an important factor, because the life span of different species of whales is naturally different. Blue whales are relatively long-lived whales, they can live to 80 years, some individuals can live to 100 years old; Some species, such as killer whales, only live to about 30 years old.
There are many other factors that affect a whale's lifespan. For example, the adequacy of food is an important factor, in the case of adequate food and rich nutrition, the life span of whales will be relatively long. There are also some external factors, such as human hunting and so on, which will have a greater impact on the life span of whales.
For mammals, they generally reach adulthood at the age of one-eighth to one-sixth of their life span. That is to say, the specific life span of whales is different, and their adult age is also different. For example, for blue whales, a species with a long life span, it may take more than ten years for them to become adults; But for some species with shorter life spans, their adult age may be under 10 years old. It can also be judged by their size, and after the whale reaches the average size of the species and no longer grows, it basically means that they have reached adulthood.
