Brachiopod Shell
Brachiopod shells have two valves that are distinct in shape and size.
The brachial valve is usually the smaller of the two valves and has supports on the inside to help support the lophophore.
The pedicle valve is usually larger than the branchial valve and has a hole through which the pedicle passes
Brachiopods are marine invertebrates, meaning they have no backbone, and are one of the few animal groups that live only in the ocean.
They live on the ocean bottom in a variety of places, including soft sediments, on rocks, reefs, or in rock crevices where some even anchor themselves with a muscular stalk called a pedicle.
To eat they filter particles and detritus (dead organic matter) out of the water with a unique feeding organ called a lophophore.
Although they have hard shells with two halves (valves), they are not related to clams (bivalves).
