Haplontic reproduction is a type of animal reproduction where the organism develops as an individual, instead of through growth from a single cell. Haplonts reproduce by means of fragmentation: they break into many parts and each part grows into an adult haplont that can then go on to produce more offspring.
The most common type of haplontic reproduction in the animal kingdom is spore formation. Spores are small, single-celled organisms that break off from a larger organism called the sporophyte and then grow into new haplonts. In these types of species, there’s no parental care; spores just have to land on an appropriate substrate where they can develop successfully (often soil or water).
In other kinds of animals, such as insects, it appears that males produce sperm cells by growing smaller versions of themselves inside their bodies which protrude through holes near their heads during mating season. This process doesn’t require any additional energy use for growth since one haplont gives rise to another at virtually no cost—and
