In zoology, the mating position of frogs and toads where the male clasps the female from behind to stimulate egg-laying.
From Latin 'amplexus' (an embrace, clasp), from 'amplectere' (to embrace). Adopted as a biological term in the 19th century to precisely describe this reproductive behavior.
Frogs in amplexus can stay locked together for hours or even days, and the pressure of the male's embrace actually triggers the female to release her eggs—it's a mechanical cue that evolved over millions of years.
