Record: a mother octopus incubates the eggs over 4 years
That would be a record in the animal world: an octopus from the ocean floor looks after her eggs for more than 4 years, small putting years to develop. The fate of such a super mom is inevitably death.

Taking care of her eggs for 4 years by eating very little, if at all, this may seem impossible. Yet that is what would an octopus Abyss. In the cold, dark waters underwater , metabolic processes are often long indeed. Therefore embryonic development could be very slow, but to what extent? Researchers at the University of Rhode Island and Monterey Bay Aquarium Research Institute had the opportunity to observe the nesting of an octopus in Monterey Bay, off the coast of California. They describe their observations in an article published in Plos One.

In May 2007, during an exploration into the canyon of Monterey, the researchers found an octopus female of the species Graneledone boreopacifica clinging to a rock face at 1,397 m depth currently monitoring her eggs. Subsequently, the researchers went back to inspect this place 18 times in four and a half years. Each time, they found the same recognizable octopus with its scars on the body. Gradually, eggs swelled and young octopuses grew.
The researchers saw the mother for the last time in September 2011 One month later, she was gone, leaving behind about 160 empty egg capsules. Therefore, it would have hatched eggs for about four and a half years, or longer than any animal known to date.
