What is a brachiopod. L. waikatoensis Pen, 1930. Synonyms. Ligula, Ligularius, Lingularius, Pharetra. Lingula is a genus of brachiopods within the class Lingulata. Lingula or forms very close in appearance have existed possibly since the Cambrian. Like its relatives, it has two unadorned organo-phosphatic valves and a long fleshy stalk.

Brachiopoda are marine animals with a large lophophore consisting of a pair of coiled or folded arms bearing ciliated tentacles. The animal is enclosed in a bivalved shell. So they are commonly known as ‘Lamp shells’. The name Brachiopoda was coined by Dumeril (1806) (brachion-arm, podos-foot).
