What is planaria?
- Planaria is a genus of planarians in the family Planariidae.
- When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.
- Currently the genus Planaria is defined as freshwater triclads with oviducts that unite to form a common oviduct without embracing the bursa copulatrix and with an adenodactyl present in the male atrium.
- The testes occur along the whole body.
- Planaria originally have habitats in dark, murky water which results in such sensitivity .
- They are also sensitive to other stimuli such as chemical gradients, vibration, magnetic and electric fields .
- Their central nervous system includes the anterior (head, brain and eyes) and middle (abdominal trunk and pharynx).
