Principle

Planarians belong to the class of the free-living flatworms (Turbellaria) and these, in turn, belong to the phylum of platyhelminthes (flatworms). They occur in both freshwater and marine environments, feeding as predators, for example, on the eggs of fishes and shrimps in aquaria. They therefore present a problem to breeders of ornamental fishes.
On account of its large number of stem cells, the planarian Dugesia tigrina is of great significance to research.
