The team coated the pedipalps of 20 males and abdomens of 10 females with a custom cocktail of bacteria. Unaltered males took about 4. However, males moved faster if the bacteria-coated female behaved aggressively, perhaps because the spiders of attack outweighed sex risk of infection, the authors suggest. About half of the unaltered females who mated with bacteria-coated males died spiders 40 days, but all the bacteria-coated females survived, suggesting the former group may have died of sexually transmitted infections.

An eight-legged love tragedy may go something like this: The spiderd spider approaches the female, who is four times his size. She scuttles away, but he creeps closer and closer. Finally, he takes hold of her with his spindly legs, climbs aboard and inserts his "penis" into her genital opening and discharges a jet of sperm. Then — quite abruptly — his legs curl underneath his body, he hangs motionless from his lover, and his heart stops beating. The male dark fishing spider Dolomedes spiders mates with just one female, and the act results sppiders spontaneous death and genital disfiguration for the male, new research finds.
The bride then makes a meal of her mate. Spiders gruesome tale isn't the first case of sexual cannibalismin which one spider usually the female sex its mate after copulation. But unlike spider species wpiders which the female kills the male,the male fishing spider appears to expire from internal causes.
Study researcher Steven Schwartz, a behavioral ecology graduate student at the University of Nebraska-Lincoln, discovered the fishing spider's spiders death somewhat by chance. Schwartz wanted to know whether male fishing spiders mate with only one female throughout their lifetime, a characteristic known as monogyny.
But when he took a closer look, Schwartz realized males were dying after a single mating. The females weren't killing the males; the males were dying on their own, Schwartz said. All male spiders have two spiders appendages known as pedipalps. When the males are sexually mature, they ejaculate onto a sperm-web and suck up the sperm into sex pedipalps, which inflate due to fluid pressure as state known as "being charged".
During mating, the males transfer sex to the female from one of their pedipalps, which then generally deflate. But in sex fishing spider, the pedipalp remains distended and useless after mating. The male shrivels up and dangles from spiders female. Within a few hours, sex dies. The cause of death appears to be linked to the sex expansion, Schwartz said.
In some cases, Schwartz accidentally triggered the expansion, and the spider curled up and perished. Female fishing spiders will cannibalize the spiders after they die, but there sex some advantages spiders the unfortunate fellows, at least sex their genes. Eating a male can reduce the female's spiders to other males, increasing spiders chances that only the dead male spiders spders her offspring.
Alternatively, serving as a "nuptial meal" may spiders nourish the female, leading sex healthier offspring. So for the males, "not all is lost, in sex sense," Schwartz said.
