Why are octopus lifespans so short? Octopus lifespan is limited by reproduction. For most octopuses the last stage of their life is called senescence. It is the breakdown of cellular function without repair or replacement. For males, this typically begins after mating.
Do octopus only live 1 year? Most species live only one to two years, and a newly imported octopus may have just weeks left. Some robust common species, such as the California two-spot octopus, get along relatively well in captivity. Others, such as the fabled but delicate mimic, do much worse.
What is the oldest living octopus? Mar 10, 2022. 330 million-year-old creature found fossilized in limestone may be the oldest known relative of octopuses, according to a study published in Nature Communications on Tuesday (March 8). The remarkably well-preserved, 10-legged creature died in a tropical bay located in what is now Fergus County, Montana.
How long do wild octopus live? It varies according to species, but octopuses, both wild and captive, live roughly 1 to 5 years.
