Lausanne, November 21: A rare video footage of bats having sex in church attic has helped scientists solve a long-lasting mystery surrounding the unusually large penises of serotine bats for mating purposes. The footage recorded by a Dutch retiree reveals that this particular species of bats use their large penises in bizarre way during non-penetrative sex. The game-changing moment was the first time that a mammal was recorded having non-penetrative mating, said the team of researchers from Europe.
Solving the enigma of the serotine bats mating was nearly impossible by the scientists until Fasel received an e-mail from a stranger named Jan Jeucken with “penis” as the first words in the subject line. Thinking the mail to be a spam he was about to delete it, but the word “Eptesicus” (meaning genus of the serotine bat) made him open the mail. He was at awe after opening the mail as it contained the video of two bats having sex that paved the way to one of the greatest unsolved mysteries.
How Do Serotine Bats Mate?
According to various reports studied by the scientists, female serotine bats possess a large membrane extending between their tail and ankles, enabling them to protect their reproductive organs. During the mating process, the males seize the females by the neck and employ their large penises akin to an additional arm to reach around and remove this membrane, as noted by the researchers. This is followed by a still embrace called “contact mating,” during which sperm is transferred.
The average time for the mating session is 53 minutes which might last to 13 hours. Fasel proposed the idea that female bats might leverage their remarkably extended cervixes to retain the sperm from multiple males for an extended period, allowing them the flexibility to decide which male they ultimately choose to bear offspring with. This process of reproduction is also called “cloacal kissing” is mostly common in birds — had never previously been observed in a mammal.
