- Order Tricladida, class Turbellaria: Planaria and other genera
- The mostly free-living Turbellaria include the planarian, Dugesia, shown above; these are found in the oceans, in fresh water, and in moist terrestrial habitats, and a few are parasitic.
- Some animals also show great ability to regenerate: small fragments of animals such as starfish, planarians, and Hydra can give rise to a whole animal.
- We then conducted competitive hybridization experiments of cDNAs between a head portion and the other body portion of planarians in order to screen genes specifically expressed in a planarian brain.
Mid 19th century: from modern Latin Planaria (feminine of Latin planarius 'lying flat') + -ian.
