It has great evolutionary significance that it has survived for long 350,000,00 years. Animal consists of stalk and shell valves and remains erect in the burrows. When not disturbed, it protrudes through the shell, with valves slightly opened. Two valves are nearly equal and convex and contain setae.

Lingula is primarily an Indo-Pacific genus and is harvested for human consumption in Japan and Australia. Lingulid brachiopods inhabit vertical burrows in soft sediments with the anterior end upward at the sediment surface (Fig 25-9A,B).

Lingula larvae have a two-valved shell. The valves are dorsal and ventral in orientation. Commonly called 'lamp shells.' They are chitinous in appearance and usually a pale amber color when preserved. Natural History: They are filter-feeders and a member of the phylum Brachiopoda.

them. Lingula (Figure 8) is an unusual brachiopod, not only because it has two similar sized valves, but also because it lives in a burrow, attached by a long pedicle. It is found today living in sandy beaches along the coast of Japan. Brachiopod or bivalve? Brachiopods (or Brachiopoda) are often confused with bivalved mollusks (clams or Bivalvia).

3. By studying the anatomy of Lingula, Terebratula and Orbicula. Cuvier (1797- 1802) placed them under the group Acephal under Mollusca. 4. The credit of coining the name of the group as Brachiopoda goes to Dumeril (1806) who placed it as a separate or­der under Mollusca.

Brachiopods (/ ˈ b r æ k i oʊ ˌ p ɒ d /), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs.Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major groups are recognized, articulate …
