to make the discovery, which required high-speed, high-resolution cameras to detect.<\/p>\n<p>Zhang and colleagues were studying sexual selection in this spider, &#8220;Philoponella prominens,&#8221; which live in communal groups of up to 300 individuals.<\/p>\n<p>Of 155 successful matings, they found 152 ended with the male catapulting and thus surviving the encounter.<\/p>\n<p>Males can mate up to six times with the same female\u2014bouncing off, climbing back up using a silk safety line, mating, and bouncing off again.<\/p>\n<p>The three males that didn&#8217;t catapult were promptly captured, killed and consumed by their partners.<\/p>\n<p>Another 30 males that were prevented from catapulting by placing a fine brush behind their dorsum all met the same fate\u2014leading the researchers to conclude catapulting is essential to avoiding sexual cannabalism.<\/p>\n<figure class=\"mb-4\" itemscope=\"\" itemtype=\"http:\/\/schema.org\/VideoObject\">\n    <meta itemprop=\"name\" content=\"These male spiders catapult at impressive speeds to flee their mates before they get eaten\"\/><br \/>\n    <meta itemprop=\"url\" content=\"https:\/\/scx2.b-cdn.net\/gfx\/video\/2022\/these-male-spiders-cat.mp4\"\/><br \/>\n    <meta itemprop=\"description\" content=\"A male spider catapulting off a female during mating.

Credit: Shichang Zhang<\/figcaption><\/figure>\n<p>&#8220;Currently, I do not know whether there is any other species can also perform the catapulting,&#8221; said Zhang, adding he planned to investigate further.<\/p>\n<p>Sexual predation by females is seen across many spider species, with various strategies for avoiding it: male nursey web spiders, for example, tie their partners up before mating.<\/p>\n<p><b>A suitable mate<\/b><\/p>\n<p>The escaping orb-weaving spiders clocked some impressive statistics: their average peak speed was 65 centimeters per second, with an acceleration of 200 meters per second squared. That&#8217;s equivalent to 20 Gs, or 20 times the acceleration felt during freefall.<\/p>\n<p>While soaring through the air, the males spin around at some 175 revolutions per second.<\/p>\n<p>The males catapult by folding the tibia-metatarsus joint of their first leg pair against females. When released, it exerts hydraulic pressure and causes the legs to expand.<\/p>\n<p>Zhang said he believes the females were judging males&#8217; sexual suitability by their ability to escape.<\/p>\n<p>&#8220;Through the catapulting, a male can escape female sexual cannibalism, and a female can choose males with high quality, because the kinetic performance may directly correlate with male&#8217;s physical condition,&#8221; he said.<\/p>\n<p>Even though they have already mated, females may go on to only accept the sperm of males that passed the test, explained Zhang. <\/p>\n<p>Spiders differ from mammals in that females have a structure known as spermatheca where deposited sperm is stored. They can decide whether to use it to fertilize eggs, or reject it by squeezing it out or changing the pH value to kill the sperm.<\/p>\n<p>Future work will confirm whether there is a correlation between male catapulting and reproductive success, said Zhang.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            These male spiders catapult at impressive speeds to flee their mates before they get eaten\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Shichang Zhang, Male spiders avoid sexual cannibalism with a catapult mechanism, <i>Current Biology<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1016\/j.cub.2022.03.051\">DOI: 10.1016\/j.cub.2022.03.051<\/a>. <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.cell.com\/current-biology\/fulltext\/S0960-9822(22)00485-7\">www.cell.com\/current-biology\/f \u2026 0960-9822(22)00485-7<\/a><\/p><\/div>\n<p class=\"article-main__note mt-4\">\n                                                \u00a9 2022 AFP<\/p>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Gotta bounce: Some spiders catapult away after sex to avoid death (2022, April 30)<br \/>\n                                                 retrieved 30 April 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-04-gotta-spiders-catapult-sex-death.html<\/p>\n<p>                                            This document is subject to copyright.
