In biology, "amplexus" refers to the mating behavior exhibited by certain amphibians, particularly frogs and toads. During amplexus, the male grasps the female from behind using his forelimbs, often around the female's waist or armpits. This position helps the male to fertilize the eggs externally as the female lays them. Amplexus is an essential part of the reproductive process in many amphibian species.
