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

The valves can be opened (by the muscles) at one end to allow water in and out of the shell ...largest-sized Mesozoic brachiopods, reaching maximum dimensions of 10 cm or greater. The brachiopod has attracted much attention not only for this large size but also for its enigmatic occurrence en masse in “Peregrinella” beds (e.g., Biernat, 1957; Ager, 1965, 1968; Thieuloy, 1972; Campbell and Bottjer, 1995a; Sandy, 1995; Kiel andThe lophophore ( / ˈlɒfəˌfɔːr, ˈloʊfə -/) [1] is a characteristic feeding organ possessed by four major groups of animals: the Brachiopoda, Bryozoa, Hyolitha, and Phoronida, which collectively constitute the protostome group Lophophorata.

Brachiopods are filter-feeding animals that have two shells and are superficially similar to bivalves (such as clams).
