Catenulida is an order of flatworms in the classical classification, or a class of flatworms in a phylogenetic approach.[2] They are relatively small free-living flatworms, inhabiting freshwater and marine environments. There are about 100 species described worldwide, but the simple anatomy makes species distinction problematic.[2]
