What 3 body features help identify a planarian?

Planarians can be identified by their distinct body features: they typically have a flattened, elongated shape that resembles a leaf, a defined head region with two prominent eye spots (ocelli) that can detect light, and a pair of lateral flaps called auricles that aid in sensing the environment. Their soft, muscular bodies also allow for movement through gliding and contracting. Additionally, planarians possess a mouth located on the underside of their body, which is part of their unique feeding system.
