Thomas (1940) reviewed feeding and respiration in the polychaete. Pomatoceros triqueter never leaves its tube. Occasionally the posterior end of the tube becomes blocked by a calcareous plate with holes in. Respiration and excretion take place using cilia action to set up currents, bringing water in and down the length of the tube and flushing it back out the same way. Respiration occurs through the surface of the body and the branchial crown.
Feeding takes place by spreading apart its branchial filaments to expose a central groove. Using cilia action, it induces a current and transports food particles towards it mouth. If particles are too large or too numerous, the tip of a filament bends over and removes it. No sorting of food particles takes place.
