Spiriferid are brachiopods filtering feeders that fed on organic particles washed around by the ocean currents. The valves (each shell side) has pronounced folds and sulcus (furrow, fissures). They lived in mud by anchoring to the sea floor with a fleshy stalk called a pedicle that protruded from the shell’s hinge.

New data on systematics of some Famennian spiriferid brachiopods from Afghanistan and Iran. D. Brice. Biology. 1999;Articulate brachiopods are known to depend on ambient fluids for their feeding and respiration under certain circumstances (e.g., Rudwick, 1970; James et al., 1992; LaBarbera, 1977, LaBarbera, 1981, LaBarbera, 1984). These ecological features strongly suggest that a function of the brachiopod shell is to direct theBrachiopods are more closely related to Bryozoans than Mollusks. The easiest differences to identify are in the shells of clams and Brachiopods. Mollusk shells are divided into left and right while Brachiopod shells are divided top (dorsal) and bottom (ventral). The shells of mollusks are usually equal on the right and left. Megastrophia and Paraspirifer acuminatus are the largest brachiopods in the Devonian Jeffersonville Limestone at the Falls of the Ohio and greater Louisville area, and they are usually between two and three inches wide.

This palaeoecological model suggest that, in an environment where the water currents were at least of the order of 0.5 m/s. the spiriferid, anchored to the substrate by its pedicle, flew in the water in much the same way as a kite flies in air. The Refrath Formation in the Bergisches Land, Germany, is an important stratigraphic unit for the study of Frasnian brachiopods. Nevertheless, few studies have been undertaken concerning its spiriferide and spiriferinide brachiopods (Cyrtospiriferidae, Verneuiliidae and Cyrtinidae).

To avoid deflection of tentacles by water flow, a slower internal flow appears to have preferred for feeding in articulate brachiopods (LaBarbera, 1977; Dhar et al., 1997).
