amplexus
Quick Summary
Amplexus is the mating embrace of some amphibians, like frogs and toads. During amplexus, the male typically grasps the female from behind with his front legs, a position that can last for days. As the female lays her eggs, the male releases sperm to fertilize them externally. This behavior is crucial for amphibian reproduction, ensuring the fertilization of eggs. In some species, amplexus occurs on land, and parental care, such as carrying eggs or tadpoles, is observed. Some amphibians have evolved direct development, bypassing the larval stage and emerging from the egg as miniature froglets.123
