Planaria exist only in fresh waters.
Many plants doesn't support salted waters or soils.
Many plants are negatively affected by saline soils.
Some organisms are not adapted to live in a saline environmement.
In my search, the nemathelminthes is also a flatworm. An example of flatworm is planaria, it is also known as hermaphroditic animal because a hermaphroditic animal have a female and male organs. The planaria also has a line in middle of its body. It will be cut in to two and another planaria is produced.
I'm going to assume that you mean 23.34g of NaCl. 1 mole NaCl = 58.442g NaCl (the atomic weight of Na and Cl in grams) 23.34g NaCl x (1mol NaCl/58.442g NaCl) = 0.3994mol NaCl
The planaria class is Turbellaria
no it does not
planeriacomes under kingdom animalea
Planaria are type of animals. Animals are not photosynthetic
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
The scientific name for planaria is flatworms in the class Turbellaria, with species such as Dugesia tigrina commonly used in research and education.
At this moment, I am conducting research and examining this very topic. It is hard to find information. Anyway, I believe magnets do not really affect regeneration in planaria and f they do- the effect is slight and not quantifiable.
No
yes
Planaria images can be found in most high school or "first" biology/zoologycollege, text books.
