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.
This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators. Most notably, animals with shorter lifespans and faster growth rates benefit more from zoos than animals with higher longevities and slow growth rates. [2]
The 100 species with longest life-spans recorded and verified [1] This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include:
Ocythoe tuberculata, also known as the tuberculate pelagic octopus or football octopus, is a pelagic octopus. It is the only known species in the family Ocythoidae . Ocythoe tuberculata is found in warm and temperate seas, especially in the Northern Hemisphere , such as the North Pacific Ocean off California.
A study of octopus DNA may have solved an enduring mystery about when the rapidly melting West Antarctic ice sheet last collapsed, unlocking valuable information about how much future sea levels ...
During reproduction, the male octopus deposits a spermatophore (or sperm packet) more than 1 m (3.3 ft) long using his hectocotylus (specialized arm) in the female's mantle. The hectocotylus is found on the third arm of male octopuses and occupies the last four inches of the arm. [39]
As one of the longest living known orcas, Granny is employed as an example in arguments against keeping orcas in captivity, referencing the allegedly reduced lifespan of captive animals. [17] As of 2025, the oldest captive orca is Corky, who has been in captivity since 1969. The average lifespan for a captive orca is 20 to 30 years.
