But after watching nearly 100 videos of bats doing just that, he recognized it was time to reevaluate assumptions.<\/p>\n<p>&#8216;We are in science, so we should be open to some new things,&#8217; he said.\u00a0<\/p>\n<p>As nocturnal animals, bats have long eluded scientists&#8217; prying eyes, said Fasel, a researcher of ecology and evolution at the University of Lausanne in Switzerland.\u00a0<\/p>\n<p>&#8216;They are quite secretive. It&#8217;s difficult to work with them, and there are still so many things we don&#8217;t know. And the things we know are quite incredible.&#8217;<\/p>\n<p>The new study was conducted by experts at the University of Lausanne&#8217;s Department of Ecology and Evolution in\u00a0Switzerland.\u00a0<\/p>\n<p>It describes the first known example of non-penetrative sex in a mammal, they claim.<\/p>\n<p>&#8216;By chance, we had observed that these bats have disproportionately long penises, and we were always wondering &#8216;how does that work?&#8217;,&#8217; said Fasel.\u00a0<\/p>\n<p>&#8216;We thought maybe it&#8217;s like in the dog where the penis engorges after penetration so that they are locked together, or alternatively maybe they just couldn&#8217;t put it inside, but that type of copulation hasn&#8217;t been reported in mammals until now.&#8217;\u00a0<\/p>\n<p>The researchers speculate that the bats may have evolved their oversized penises in order to push aside the female bats&#8217; tail membranes, which females may use to avoid sex.\u00a0<\/p>\n<p>&#8216;Bats use their tail membranes for flying and to capture the insects, and female bats also use them to cover their lower parts and protect themselves from males,&#8217; said Professor Fasel.<\/p>\n<p>&#8216;But the males can then use these big penises to overcome the tail membrane and reach the vulva.&#8217;\u00a0<\/p>\n<p>The\u00a0serotine bat (Eptesicus serotinus) is found throughout Asian and Europe, including the southern half of the UK, according to the Woodland Trust.\u00a0<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/i.dailymail.co.uk\/1s\/2023\/11\/20\/16\/78021993-12762845-The_serotine_bat_Eptesicus_serotinus_is_found_throughout_Asian_a-a-15_1700496215976.jpg\" height=\"425\" width=\"634\"><\/p>\n<p>The serotine bat (Eptesicus serotinus) is found throughout Asian and Europe, including the southern half of the UK<\/p>\n<h3>READ MORE Wrinkle-faced bats lower a fold of skin under their chin before sex\u00a0<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/i.dailymail.co.uk\/1s\/2023\/11\/20\/16\/35564756-12762845-The_skin_mask_of_the_males_is_only_lowered_immediately_before_se-a-16_1700496215976.jpg\" height=\"181\" width=\"274\"><\/p>\n<p>The skin mask of the males is only lowered immediately before sex\u00a0<\/p>\n<p>The species lives in open woodland, hedgerows, parkland, and pastures but when it hibernates in the winter it can be found taking shelter in old buildings, such as disused chimneys and inside walls.\u00a0<\/p>\n<p>To learn more about the secret sex lives of the species, researchers set up cameras at two locations \u2013\u00a0a church attic in the Netherlands and a\u00a0bat rehabilitation centre in\u00a0Ukraine.\u00a0<\/p>\n<p>The experts were able to get close-ups of the bat genitalia during sex by placing cameras behind a grid that the bats could climb on.\u00a0<\/p>\n<p>Altogether, the team analysed video footage of 97 mating events, which all revealed that the little mammals do not engage in penetrative sex.\u00a0<\/p>\n<p>The researchers did not observe penetration at any point during the recorded mating events, although what they did observe was illuminating.\u00a0<\/p>\n<p>During mating, the male bat would grasp their female partner by biting her neck and moving their pelvis (and fully erect penis) in a &#8216;probing&#8217; fashion.<\/p>\n<p>Only once he had made contact with the female&#8217;s vulva, the male remained still and held its partner in a long embrace.\u00a0<\/p>\n<p>On average, these interactions lasted less than 53 minutes, but the longest event extended to a whopping 12.7 hours.\u00a0<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/i.dailymail.co.uk\/1s\/2023\/11\/20\/16\/78021999-12762845-For_the_study_researchers_set_up_cameras_at_two_locations_a_chur-a-17_1700496215977.jpg\" height=\"480\" width=\"634\"><\/p>\n<p>For the study, researchers set up cameras at two locations &#8211; a church attic in the Netherlands and a bat rehabilitation centre in Ukraine<\/p>\n<p>&#8216;During this time we noted several social calls, probably emitted by the female,&#8217; the study authors say.\u00a0<\/p>\n<p>Following copulation, the female bats&#8217; abdomens appeared wet, suggesting the presence of semen, but further research is needed to confirm that sperm was transferred.\u00a0<\/p>\n<p>Female bats seem to use this strategy to choose the suitable mate to parent their offspring, even after the deed has already been done.<\/p>\n<p>&#8216;We still don&#8217;t know the mechanism behind this,&#8217; Fasel says.
