Spiders like it rough too Scientists discover 8 legged bondage action

Scientists have discovered that saucy arachnids practice some rather kinky games with silk when they are getting their leg over – all eight of them. 

Yet rather than adding more spice to the love-making, tying up sexual playmates can be vital for some spider species as it stops them from being gobbled up. 

The web’s sexiest secrets have been put under scrutiny by academics at the University of Nebraska-Lincoln. 

They have been studying nursery-web spiders – scientific name Pisaurina mira – to see how males use silk to stop themselves becoming a post-coital snack. 

Researchers paired up spiders, with some males able to spin protective strands of silk and others prevented from producing the thread, which is used to bind a female’s legs during sex. 

What they discovered was that although males that could not restrain females were still able to mate, they were far more likely to be eaten than those males who had bound up their partners. 






They also discovered that it was the longer legged males with larger bodies, making them more successful at wrapping up females, were more likely to survive. 

Another advantage of restraining females was that it allowed “more insertions,” say scientists. 

Alissa Anderson, a behavioural ecologist at the University of Nebraska-Lincoln, who co-authored the study published in Biology Letters, says it is conflict between two competing desires, the female”s urgent need for sustenance and the male”s need to survive, that can lead to unusual sexual-survival strategies. 

She explained to Live Science how a newly fertilised female with eggs to nourish sees her mate’s value transform from sexual partner to “resources for her developing offspring.” 

In some species, females who cannibalise their mates go on to produce more offspring with a better chance of survival. 

To combat this, some species of male spider play dead to avoid being eaten after sex while in others the males use a substance to sedate females into a state of unconsciousness. 

Other males simply jump on females while they are tucking on to their previous mates.
