Do Brachiopods Have Shells?

Systematic and Taxonomic History. These creatures have two shells, a brachial and a pedicle valve, secreted by characteristic mantle folds, which are extensions of the metasome and contain metacoelomic mantle canals. Brachiopods have rows of setae, each secreted by one cell, along the mantle edges.

How many shells do brachiopods have?

Brachiopods have two valves (shells) that are generally of unequal size and shape, but the right and left halves of each valve mirror each other. Near the tip of the bottom shell (the pedicle valve), a fleshy stalk (the pedicle) emerges through a hole (the pedicle opening) and attaches the animal to the sea bottom.
