Unlike most other octopus species, whose lifespans normally span only one year, the giant Pacific octopus has a lifespan of three to five years. [3] They reach sexual maturity at one to two years of age. [34] Gonadal maturation has been linked to the optic gland of octopuses which has been compared functionally to the vertebrate pituitary gland ...

This also makes it the longest-living octopus – most octopuses only live for 1 or 2 years – which this octopus beats with its brooding period alone. [ 4 ] [ 5 ] Female Graneledone boreopacifica tend to brood their eggs between the depths of 1,200 and 2,000 metres (3,900 and 6,600 ft); the eggs were never unattended.
H. maculosa has a very short life span with a large importance placed on reproduction. The average life span of a southern blue ringed octopus is around seven months. The octopus reaches sexual maturity at around four months old, at which time it focuses its last few months of life towards copulation and breeding.
In just the past two decades, 2000 — 2019, the average global life expectancy increased from 66.8 years to 73.4 years while healthy life expectancy has also improved by 8% over the same period.
The species has a short life span, with estimates between under two years [9] and three to four years. [3] Females lay from 400 [11] up to 1,200 eggs at a time; [3] the eggs are very large, [11] up to 28 millimeters. [5] The size of the eggs suggests that hatchlings are benthic. [3] [11]
