The phylum name for planarians is Platyhelminthes, which includes flatworms like the planarian. They are characterized by their flattened body shape and bilateral symmetry.
A common feature of phylum Platyhelminthes is their flattened, ribbon-like body shape, which gives them their name (platy meaning flat). They also lack a body cavity (coelom) and have a simple nervous system with nerve cords and ganglia.
Platyhelminthes breathe using their entire body. Being flat, oxygen diffuses quickly across the skin and to all parts of the body, so they don't need a blood circulatory or respiratory system.
