Neospirifer Neospirifer Neospirifer is a brachiopod from the order Spiriferida . Spiriferids get their name from the arrangement of their internal organs.
Brachiopods have food-gathering organs called lophophores.
The lophophores have tentacle-like cirri growing from them. In turn, the cirri have tiny hair-like cilia growing from them. These cirri and cilia set up a waving motion that circulates food laden water into the animal's mouth. Spiriferids had their lophophores arranged in a pair of spirals inside their shells. Neospirifer had a very long hinge line with fine plications, or currogations, radiating out from the center of the hinge line.
