Spider's Detachable Penis Finishes Without Him

Sex can be dangerous, even deadly if your partner has plans to eat you. When the male orb-web spider has its first, and sometimes last, sexual encounter it has a trick up its sleeve: detachable genitalia which keep pumping even after their owner's moved on.

The orb-web spider Nephilengys malabarensis is sexually cannibalistic and the male has detachable genitals. These spiders have at most two chances to mate : They have a pair of sperm-transferring organs, actually called their "palps" but analogous to a penis, which detach from their bodies when they disengage from mating — either when the female pushes them away and possibly eats them or they successfully run away to risk death another day.
