Spawning

Spawning is breeding and conception outside the animal body, most commonly found in species living in aquatic environments.

Spawning then happens with the female laying her eggs in the waters, while a male covers these with sperm, most often at the same time and close to the eggs.

Typical species that spawn are fish and amphibians, while most mammals and insects have internal conception.
