What is the longest lived octopus?
Northern Giant Pacific Octopus
The northern giant Pacific octopus (Enteroctopus dofleini) is the largest, longest-lived octopus species. Although its average length and mass are 5 metres and 20 to 50 kilograms respectively, the largest recorded individual was 9.1 metres long and weighed 272 kilograms. They typically live for three to five years.
The longest-lived octopus is the giant Pacific octopus (Enteroctopus dofleini), known for its remarkable longevity among cephalopods. This species can live up to 5 years or even more, depending on various factors such as habitat, diet, and reproductive cycle. The life span of an octopus is influenced by its growth rate, metabolic rate, and the energy it expends in reproduction.
Giant Pacific octopuses typically inhabit the coastal waters of the North Pacific, ranging from Japan to California, and they prefer deep, cold, and rocky environments. They have a relatively slow growth rate, taking years to reach maturity. During their lifespan, they undergo a complex life cycle that involves a period of intense growth, followed by reproduction and eventual senescence.
Reproduction is a significant factor influencing their life expectancy. After mating, females invest a substantial amount of energy in laying and guarding eggs, during which they cease feeding and often die shortly after their eggs hatch. Males also die soon after mating. This combination of slow growth, lengthy maturation, and intense reproductive efforts contributes to the octopus’s relatively long lifespan compared to other cephalopods.
Can octopus live for 10 years?
In general, octopuses have a relatively short lifespan. For example, the Common Octopus, Mimic Octopus, and Blue-Ringed Octopus live for around 12 – 18 months whereas the Giant Pacific Octopus can have a lifespan of 3-5 years!
Octopuses, including various species like the common octopus (Octopus vulgaris), typically have a relatively short lifespan compared to other marine creatures. Most octopus species have a life expectancy ranging from as short as 6 months to around 3 to 5 years. However, there are a few exceptions, such as the giant Pacific octopus (Enteroctopus dofleini), which can live up to 5 years or even longer under optimal conditions.
Reaching the age of 10 years is quite uncommon for octopuses. The factors influencing an octopus’s lifespan include species, environmental conditions, habitat, diet, predation, reproductive activities, and overall health. Factors like stress, injuries, and diseases can also impact their longevity.
Giant Pacific octopuses, as mentioned earlier, are among the longest-lived octopus species. They have the potential to survive for over 5 years, provided they have access to a suitable habitat with ample food resources and minimal threats from predators.
Octopuses are highly intelligent and fascinating marine creatures, exhibiting complex behaviors and adaptations. Their relatively short lifespans are due to their unique life cycle, which involves rapid growth, intense reproductive efforts, and subsequent senescence. Despite their shorter lifespans compared to some other marine animals, octopuses play a crucial role in marine ecosystems and contribute to the balance and health of the underwater world.
What is the lifespan of a giant octopus?
Four To Five Years

The giant octopus, scientifically known as the giant Pacific octopus (Enteroctopus dofleini), boasts an impressive but relatively limited lifespan within the realm of cephalopods. On average, these magnificent creatures can live between 3 to 5 years in the wild. However, under ideal conditions with an abundance of food, a suitable habitat, and protection from predators, some individuals have been known to exceed this average and live up to 5 to 7 years. It’s exceptionally rare for a giant octopus to reach a decade in age.
Their lifecycle includes a period of rapid growth, reaching maturity within the first two to three years of life. Following maturation, they focus on reproduction, during which they invest a significant amount of energy. The female octopus lays thousands of eggs and dedicates herself to guarding and caring for them, ceasing to feed during this period. Tragically, this intense effort often leads to the end of her life shortly after the eggs hatch.
Environmental factors, availability of food, and predation risks significantly influence their lifespan. Octopuses are vulnerable to various predators, including sharks, larger fish, and sometimes even other octopuses. The complex and intriguing life cycle of the giant Pacific octopus contributes to its overall lifespan, showcasing the delicate balance of survival and reproduction in the marine world.
