That's because they're semelparous, which means they reproduce just once before they die. The maturation of the reproductive organs appears to be driven by secretions from the optic gland. These same secretions, it seems, inactivate the digestive and salivary glands, which leads to the octopus starving to death.That's because they're semelparous, which means they reproduce just once before they die.
