Octomom

Deep-sea explorer Bruce Robeson and evolutionary neuroscientist Yan Wong detail the remarkable life cycle of a deep-sea octopus dubbed "Octomom." This creature spent over four years brooding a clutch of 160 eggs on a vertical rock face in the Monterey Canyon, abstaining from food the entire time. Her survival during this prolonged starvation relies on the optic glands, which release specific chemicals—including steroids and insulin—that sustain her body while other physiological processes shut down. This extreme maternal investment, characterized by constant vigilance against predators and eventual death upon hatching, represents the longest known brooding period in the animal kingdom. While the exact evolutionary driver remains a mystery, the behavior highlights a profound, focused commitment to offspring survival in the harsh, cold conditions of the deep ocean.
