Size: 0.3-1.5 mm. ... They are filter-feeders and a member of the phylum Brachiopoda.Subphylum Hexapoda. The name Hexapoda denotes the presence of six legs (three pairs) in these animals, which differentiates them from the number of pairs present in other arthropods. Hexapods are characterized by the presence of a head, thorax, and abdomen, constituting three tagma. The thorax bears the wings as well as six legs in three pairs.The position of brachiopods in the system of Metazoa remains uncertain. There are no strong reasons for changing the traditional division of the phylum Brachiopoda into the classes Inarticulata and Articulata. The class Articulata is divided into the subclasses Orthata, Strophomenata, Spiriferata, and Terebratulata.
