Incredibly spider species die because of ...

After sexual intercourse, male spiders are often killed by carnivorous spiders, but with fish spiders, male spiders die because . 'upper code'.

This fact was discovered by chance. Steven Schwartz, a new graduate student in behavioral ecology at the University of Nebraska-Lincoln, wants to find out whether male spiders (with the scientific name Dolomedes tenebrosus ) mate with just one female. throughout life or not. When he observed, he noticed that the male spider had died itself immediately after mating with the female spider, before being eaten by the spider.

The cause of this death was explained by the researcher as follows: all male spiders have 2 front parts, called pedipalps . When they reach mating age, they release sperm into the sperm membrane and suck sperm into the pedipalps, causing it to swell. When mating, the male will release sperm into the female from a pedipalps.

Male fish spider died because of "upper code" right after mating with female spider.

However, unlike other spiders, the pedipalps will collapse, the pedipalps of the fish spider will still stretch and become useless even after mating. After that, the male spider shrank and died after a few hours.

'The cause of this death is related to the puffiness of pedipalp ' , Schwartz said.

After the male spider dies, the female spider will eat it and this is really beneficial for the misfiring spider because when it comes to eating the male spider, the female spider will have no chance of mating with another, meaning it will The father of the children is about to give birth.
