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 ...
The giant Pacific octopus (Enteroctopus dofleini) is often cited as the largest known octopus species. Adults usually weigh 10–50 kg (22–110 lb), with an arm span of up to 4.8 m (16 ft). [19] The largest specimen of this species to be scientifically documented was an animal with a live mass of 71 kg (157 lb). [20]
The common octopus (Octopus vulgaris) is a mollusk belonging to the class Cephalopoda. Octopus vulgaris is one of the most studied of all octopus species, and also one of the most intelligent. It ranges from the eastern Atlantic, extends from the Mediterranean Sea and the southern coast of England , to the southern coast of South Africa.
The lifespan may be long or short, though the species technically does not "age". Individuals of other species have been observed to regress to a larval state and regrow into adults multiple times. The hydrozoan species Turritopsis dohrnii (formerly Turritopsis nutricula ) is capable of cycling from a mature adult stage to an immature polyp ...

The California two-spot octopus (Octopus bimaculoides), often simply called a "bimac", is an octopus species native to many parts of the Pacific Ocean including the coast of California. One can ...
The U.S. has the widest health span-lifespan gap. The average life expectancy in the U.S. is 77.5 years, according to the Centers for Disease Control and Prevention. But Americans outlive their ...
The growth rate of the curled octopus is quite rapid and its life span is generally short at 1–5 years, although there may be some variation between warmer and colder areas. The curled octopus matures at around 1 year (on reaching a total length of 12–40 cm or 4.7–15.7 in for females, slightly smaller for males) and with 1,000–5,000 ...
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.
