Planaria torva is a species of planarian in the family Planariidae.[1] When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.[2]

Diet[edit]

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.[3] In the United Kingdom, P. torva is a successful predator of the invasive New Zealand mud snail (Potamopyrgus jenkinsi).[4]
