Planaria is a genus of planarians in the family Planariidae. It is currently represented by a single species, Planaria torva,[1] which is found in Europe.[2]


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.[3]


The food of P. torva consists of freshwater gastropods, tubificid worms, and freshwater arthropods, such as isopods of the genus Asellus and chironomid larvae.[4]
