Brachiopods , phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" 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.

Brachiopods are rare in modern oceans, but were very common in the past (only 325 living species but more than 12,000 fossil species).

Brachiopod Fossils. The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels.

Brachiopods are solitary creatures that inhabit the seafloor across a variety of habitats. Because they are sessile (unmoving), they filter food particles and nutrients out of the water.

Brachiopods live exclusively on the sea floor; they are therefore called Benthic animals. Most brachiopods live on the shallow continental shelf. However, there are a few species that can live in depths exceeding 5000m. Most brachiopods tolerate only normal marine salinity, but a few species, such as the ligulides, can live in brackish salinities.

Superficially, brachiopods may look like bivalves, but the two are not related. One of the biggest differences between brachiopods and bivalves lies in their symmetry. Both have bilateral symmetry, but the plane of symmetry in brachiopods is vertical rather than horizontal (Figure 7.32).
