Planaria primarily reproduce asexually through a process called fission, where the organism divides into two or more parts, each regenerating into a complete individual. They can also reproduce sexually, possessing both male and female reproductive organs, and engage in copulation to exchange sperm. After fertilization, the eggs are laid in a protective casing. This dual reproductive strategy allows planaria to adapt to varying environmental conditions.
Guppies have the most advanced reproductive methods.
The planaria class is Turbellaria
planeriacomes under kingdom animalea
sp refers to a planaria where the actual species is undetermined...or sometimes because several species of planaria have similar appearance or behavior and have been used in a study.
Usually a planaria regeneration experiment involves cutting the planaria into different parts. The head can be separated from the tail or the planaria can be cut lengthwise, etc. After cutting the planaria, it will be observed for few days noting how the organism regenerate its lost body parts.

Planaria prefer dark environments
NaCl, also known as salt, can affect planaria by disrupting their osmoregulation. Planaria have a delicate balance of salt concentrations in their cells to maintain proper water and ion balance. Excess salt can cause dehydration, while insufficient salt can lead to swelling and bursting of cells in planaria.
The planaria scientific name is called Planariidae. It is not a species so the binomial name could not be determined. Planaria are non-parasitic flatworms.
Spores
No
No, planaria do not do photosynthesis. They are free-living flatworms that are primarily carnivorous, feeding on small organisms in their environment. They rely on external sources of food for their energy needs.
Some do. Invertebrate have a wide variety of reproductive methods.
