(From Wikipedia) A planarian usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes.
FACT: Planarians demonstrate simply ridiculous regenerative abilities, able to regrow so well that a planarian split down the middle will simply become two planarians!
