Octopus is a kind of marine organism, and their life span is generally not too long. The average life span of octopus is about 3 years old. Specifically, the life span of octopus is not very certain, some octopus life span is longer, can live to about 4 years old, but generally not more than 5 years; Some octopuses have a shorter life span, perhaps as short as two years or less.
There are many factors that affect the life span of octopus. For example, species is an important factor, octopus species are very many, all the world's octopus species may add up to hundreds of species, the life span of these octopuses may be different. Giant octopuses, for example, have a relatively short life span. Moreover, the living environment will also have a greater impact on the life span of octopus, cultured octopus may live longer, wild octopus life span is shorter. Moreover, an important factor is human predation, if octopus life is not human predation, their life span will naturally be longer.
As mentioned above, there are many kinds of octopus in the world, and there may be hundreds of kinds. The size of these different species of octopus is different, so the question of how old an octopus is is uncertain. For example, the "arboreal octopus" may be relatively small, some only 5 centimeters long, but some individuals can grow to a larger size, judging from their adult size is not very accurate. In addition, there are some large octopuses, such as the Pacific octopus, which are generally very large when they grow up.
