Errantia is a diverse group of marine polychaete worms in the phylum Annelida. Traditionally a subclass of the paraphyletic class Polychaeta,[4] it is currently regarded as a monophyletic group within the larger Pleistoannelida, composed of Errantia and Sedentaria.[2] These worms are found worldwide in marine environments and brackish water.
