A planarian is one of the many flatworms of the traditional class Turbellaria. It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelm ...
flatworms including species that mainly inhabit salt water environments. However, some species are also known from freshwater or brackish waters.

Taxonomy and phylogeny
History
The Maricola group was first proposed by
Hallez in 1892. He recognized three
families
Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Ideal ...
: Otoplanida, Procerodida and Bdellourida. Two years later, in 1884, Hallez renamed these families as Otoplanidae, Procerodidae and Bdellouridae. In 1906
Böhmig classified the Maricola in two families and five subfamilies: Procerodidae (Euprocerodinae, Cercyrinae, Micropharynginae) and Bdellouridae (Uteriporinae, Eubdellourinae). In 1909 Wilhelmi wrote a monograph on the group in which five families were described: Procerodidae, Uteriporidae, Cercyridae, Bdellouridae, Micropharyngidae. Von Graff used the same classification in 1916. In 1989
Sluys recognized the six present families on the basis of
phylogenetic analyses
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups o ...
