Evolution Of Male Spiders In Response To Female Cannibalism.

The study concluded that male spiders evolved as a direct response to female cannibalism. Scientists have discovered a new way male spiders avoid being eaten after mating. Male spiders at risk of getting eaten by females have evolved. After mating, some species of female spiders kill and eat their partners. According to a peer-reviewed published by Shichang Zhang, An ecologist at Hubei University in China, the catapulting spiders are showing a new will to live. Some males can induce acquiescence in their female partner, for example, knocking her out to escape. Others tie the females up with silk. Others come bearing gifts, like a silk-wrapped prey item, to presumably occupy the female while attempting to mate. The study oversaw 155 matings in which 152 male spiders used this behaviour. The three male spiders that didn't were captured, killed and consumed by the females. Male spiders that can mate multiple times will increase their chances of paternity.
