The orb-web spider Nephilengys malabarensis is sexually cannibalistic and the male has detachable genitals.
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.
For spiders this breakage of male’s sperm-transferring organ is common, says researcher Daiquin Li, of the University of Singapore, but it's usually just the tip.
"However, some spider species exhibit extreme genital mutilation or the 'eunuch phenomenon,' where males castrate their entire pedipalp(s) during copulation," Li, author of a new study on this process, told LiveScience.
Extreme sacrifice
This eunuch behavior is a pretty confusing concept to most researchers: They (like most men reading this) really couldn't think of a way that having a break-off penis could be a good thing. They previously thought that this full breakage was just a mistake (since what good, evolutionarily speaking, is a male unable to have sex?), but Li believes it must have some advantage for the male — possibly storing or transferring more sperm.
The researchers collected 50 virgin orb-web spiders — 25 each, male and female — from Singapore and raised them in the lab until they reached sexual maturity. They were mated in pairs by placing the smaller males into the female's web. The researchers recorded how long they mated, who stopped the mating, and how much palp broke off. Eighty eight percent of the time the spiders left the whole palp in the female.
After mating they left the palp in the female for different amounts of time (up to 20 minutes), then measured how much sperm was left in the palp and in the female's sexual organs. The researchers found that the detached genitalia continued to transfer sperm after sex ended.[/release]

DEAR GOD. Imagine swarms of spider penis rushing towards you while cumming.
The horror.
"It's usually just the tip"
I couldn't help but laugh at that. Poor guy.
I somehow read the spider as "sniper" and wondered what kind of things were he doing...
But yeah this is pretty interesting

We must eliminate the Spiders.
Who decided they should study the way spiders use their dicks?
What a cocky spider, I must say.
Nice multi task right there...

Seriously, not a good thing to see.
Scumbag dick?
I thought this was already well known, or maybe that was another invertebrate.
I know I heard about a fish that does something similar, except the male becomes completely attached to the female and eventually dies, leaving nothing but a penis and testes.
another reason to be creeped out by these things
like i needed more.
DEAR GOD THE HORROR!

Its basically like "Oh shit, bailout" *penis snaps off* and the spider scurries away.
