UNDATED (WKRC) – Scientists may have finally figured out why the octopuses torture and eat themselves after mating. A new study suggests that mother octopuses take part in this behavior because of the chemical changes that occur when they are close to laying their eggs.
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.
How old is the oldest 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.
