These Spiders Eat Their Mothers' Dead Bodies
Most kinds of spiders live solitary lives, but some, like the species Stegodyphus dumicola, live in groups. These spiders perform acts that benefit the group—at the expense of the individual. All adult females care for the young, regurgitating a nutritious fluid that literally drains them of life. The spiderlings then eat their bodies. Even females that never mate do this, perhaps because their sisters' and cousins' DNA—similar to their own—will make it to another generation.
