Female Frogs Fake Death to Escape Unwanted Mating Advances, Study Reveals Recent studies have uncovered that female European common frogs (Rana temporaria) employ a remarkable tactic to evade unwanted male advances during the breeding season: they feign death. This behavior, known as “tonic immobility,” involves the female frog becoming completely motionless, often with limbs outstretched, mimicking the appearance of death. This strategy effectively deters persistent males, allowing the female to escape potential mating attempts.  Researchers observed that during the species’ brief and intense breeding period, multiple males may attempt to mate with a single female simultaneously, forming what is known as a “mating ball.” Such situations can be perilous for females, sometimes leading to drowning or other injuries. To counteract this, females have developed several avoidance behaviors: • Rotating: The female twists her body to dislodge the male’s grip. • Release Calls: Emitting sounds similar to those made by males to signal release, tricking the male into letting go. • Tonic Immobility: Feigning death to discourage the male’s interest. These findings highlight the active role female frogs play in mate selection and their strategies to ensure survival during the breeding season.  The study, published in the journal Royal Society Open Science, emphasizes that female European common frogs are not as passive during mating as previously thought. Their ability to employ such tactics demonstrates a complex behavioral adaptation to the challenges posed by their reproductive environment

I guess its better to fake death to avoid sex with persistent sexually aggressive males who knows what is going on in their heads?
