Default An Anomaly in Mating: Self-Castration Raises Reproductive Success

"Males of a tropical species of orb-web spider castrate themselves, either partly or fully, after mating. It might seem a self-destructive habit, but in removing their genitals, a new study reports, the spiders are actually improving their reproductive success.
By becoming a half eunuch or full eunuch, the spider reduces its weight by 4 to 9 percent. It then stands guard by the female it has mated with. Its lighter weight allows it to better fend off other males."
