Male serotine bats have penises seven times longer than female vaginas, using this anatomy to bypass the uropatagio membrane and achieve contact-based mating lasting up to 12 hours. Researchers analyzed 97 mating encounters from video recordings, discovering sensory hairs and suction-like structures on the penis that facilitate vulva location and sustained contact during reproduction.
