the tenderness
by Douglas J. Lanzo
of a mother’s touch
eight arms caressing eggs
Mother octopuses are so devoted to ensuring the health and survival of their eggs that they outdo all of nature in their supreme final acts of sacrifice. And these acts last much longer than you would ever imagine. Brushing her eggs to keep them free of silt and sediment, blowing water over them to diffuse oxygen through their membranes and constantly guarding her eggs with eight arms to ward off reef fish, eels and starfish, a mother octopus dedicates 100% of her time, energy and attention to her brood.
This means that from the moment she strands her eggs and attaches them to the walls of her den, she remains with them, staying with them day and night for the remainder of her life (which last another 1 to 4 months for a Common Octopus, 5 to 10 months for a Great Pacific Octopus and about 53 months for a deep-sea octopus). During this time, the mother octopus slowly starves to death in a process known as senescence, passing away just before or at the same time as her eggs begin to hatch. This ensures that the mother octopus does not cannibalize her young and provides them a greater change of survival by diverting predators to feast on her rather than on the myriad of new hatchlings.
In a fascinating discovery, scientists have learned that a mother octopus’ senescence is triggered by an optic gland switching from producing hunger-driving hormones to producing a toxic blend of cholesterol precursors and steroids. It provides her just enough strength to care for, caress, fan, siphon and guard her eggs, but not enough energy to survive their birth. An impeccably timed act of ultimate sacrifice and devotion, driven by science and, perhaps, by just a touch of tender loving care.
