Some planarians (such as the genera Planaria, Artioposthia, Arthurdendyus, Coleocephalus and Newzealandia) have a series of finger-like projections, called adenodactyls, near the male and female atria. Adenodactyls contain glands and produce several secretions believed to be useful during reproduction. [7]
In sexual reproduction, the mating generally involves mutual insemination. Thus, one of their gametes will combine with the gamete of another planarian. Each planarian transports its secretion to the other planarian, giving and receiving sperm. Eggs develop inside the body and are shed in capsules. Weeks later, the eggs hatch and grow into adults.
Planaria is a genus of planarians in the family Planariidae. Due to its excellent ability to regenerate, species of Planaria has also been used as model organisms in regeneration studies. [ 1 ] When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual. [ 2 ]

Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. [2]These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. [3]
Species of the genus Microplana are characterized by having an elongate, rounded body and generally only two eyes. The copulatory apparatus has a permanent conical penis with a muscular bulbus projecting into a short atrium.

The biologist Thierry Lodé proposed (2001, 2012) five modes of reproduction based on the relationship between the zygote (fertilised egg) and the parents: [1] [2]. Ovuliparity: fertilisation is external, the oocytes being released into the environment and fertilised outside the body by the male. [1]
