No, planaria do not have antennae. They are flatworms belonging to the class Turbellaria and have a simple body structure. Instead of antennae, planaria have structures called ocelli, which are light-sensitive eye spots that help them detect changes in light. Their sensory functions are primarily carried out through other specialized cells and structures on their bodies.
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.
No
crayfish have six antennae
Mollusks do not have antennae at all. Insects have antennae.
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.
Planaria images can be found in most high school or "first" biology/zoologycollege, text books.
