According to a recent research, female cephalopods disfigure themselves to death due to a sudden drop in steroid hormone concentrations after they produce eggs.
Octopus & squid are members of the cephalopod family, which has the biggest central nervous networks and the highest brain-to-body weight proportions among spineless animals. To the dismay of those expecting a long lifespan, cephalopods have a relatively limited lifespan.
Scientists, such as those at the University of Chicago, indicate that after depositing a nest of eggs, mom octopuses stop eating and begin to deteriorate. The parent octopuses are far gone by the moment the eggs are laid. Octopus optic glands, which are related to human pituitary glands, are thought to be responsible for their strange maternal behavior.
According to a recent research, researchers have discovered that the optic gland of maternal octopuses suffers a major change in cholesterol conversion, which leads in drastic alterations in the chemical messengers generated. Changes to cholesterol metabolism may have a significant impact on lifespan and behavior in other species, especially humans. In both soft-bodied cephalopods and vertebrates, the steroid compounds perform identical activities, according to the scientists who made the discovery.
Scientists examined the substances generated by the ocular gland in mother octopuses after previous studies suggested that the organ has a role in the damaging behavior of female cephalopods. We’ve discovered that octopuses, like rats, have two key mechanisms for making cholesterol.
Persistent self-injury similar of octopus end-of-life actions may be seen in kids with the illness. Scientists believe that disrupting this cholesterol synthesis mechanism in octopuses like it does in other species, has serious implications. Experts seek to learn more about the smaller Pacific striped octopus in upcoming studies to see why the creatures in that study didn’t self-destruct upon reproducing.
To avert the sad octopus death cycle, researchers want to analyze the optic glands of the striped octopus then contrast their findings with those from more recent studies.
