Trigonulina d'Orbigny, 1853 is a genus of small carnivorous bivalves in the family Verticordiidae.[1][2] It was first named by Alcide d'Orbigny with the type taxon T. ornata in 1853, though T. novemcostata was named first originally as Hippagus novemcostatus in 1850 which is now unaccepted.[3] Trigonulina shells are known to be extremely small, ranging from about 1-3.6 millimeters long.[2] They live at depths of 18-850 meters below the ocean's surface and burrow under sand to feed on microscopic crustaceans using adapted inhalant siphons.[2] T. ornata lives in the western Atlantic Ocean[2] while T. novemcostata is native to the South China Sea.[3]
