The grim, final days of a mother octopus are dutiful: leave her and her eggs alone
Octopuses are the undisputed darlings of the science internet, and for good reason. They’re incredibly intelligent problem-solvers and devious escape artists with large, complex nervous systems. They have near-magical abilities to change colors, skin textures and shapes instantaneously, and they can regenerate missing arms at will.
However, the final days of a female octopus after she reproduces are quite grim, at least to human eyes, says a 2018 study by the University of Chicago Medical Center. Octopuses are semelparous animals, which means they reproduce once and then they die. After a female octopus lays a clutch of eggs, she stops eating and wastes away; by the time the eggs hatch, she dies. If you’re wondering, the males don’t get off any easier. Females often kill and eat their mates; if not, they die a few months later, too. — ScienceDaily
