But unlike spider species in 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 curious 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 front appendages known as pedipalps.
When the males are sexually mature, they ejaculate onto a sperm-web and suck up the sperm into their pedipalps, which inflate due to fluid pressure as state known as "being charged". During mating, the males transfer sperm to the female from one of their pedipalps, which then generally deflate. But in the fishing spider, the pedipalp remains distended and useless after mating. The male shrivels up and dangles from the female.
Within a few hours, he dies. The cause of death appears to be linked to the pedipalp expansion, Schwartz said. In some cases, Schwartz accidentally triggered the expansion, and the spider curled up and perished.
Female fishing spiders will cannibalize the males after they die, but there are some advantages for the unfortunate fellows, at least for their genes.
