Planaria Cincinata
''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. When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual. When decapitated, they retain their memories. Description 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 (Paskin et al., 2014). They are also sensitive to other stimuli such as chemical gradients, vibration, magnetic and electric fields (Deochand et al., 2018). Their central nervous system includes the anterior (head, brain and eyes) and middle (abdominal trunk and pharynx) (Deochand ...

Planaria Torva
''Planaria torva'' is a species of Tricladida, planarian in the family Planariidae. When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual. Diet The food of ''P. torva'' consists of freshwater gastropods, tubificid worms, and freshwater arthropods, such as isopods of the genus ''Asellus'' and chironomid larvae, although it shows a clear preference for snails. In the United Kingdom, ''P. torva'' is a successful predator of the invasive New Zealand mud snail (''Potamopyrgus jenkinsi''). References Continenticola {{flatworm-stub ...
