Mating facts for kids
Mating is the pairing of opposite-sex or hermaphrodite organisms. It is usually for sexual reproduction. Some definitions limit the term to pairing between animals. Other definitions extend the term to crossing in plants and fungi. It is usual for mating in plants or fungi to be called cross-fertilization, or "crossing" if the offspring have DNA from both genetic sources.
Mating may also lead to external fertilization. This is done by amphibians, most fish, many lower animals, and plants. Many aquatic species just spread their eggs and sperm in the water at one specific time of year. That time varies between species.
For some hermaphroditic species, copulation is not needed because the parent organism can self-fertilize (autogamy). In some flowering plants self-pollination can happen within the same flower, and some hermaphrodite animals self-fertilize. Many gastropods are hermaphrodite, and do simultaneous copulation in pairs. So do earthworms.
