Meaning and Definition
A marine invertebrate animal belonging to the phylum Brachiopoda, characterized by a lophophore for feeding and having a two-valved shell, often resembling a clam in appearance but with a different anatomical structure.
In a broader scientific context, any member of this ancient, largely extinct phylum, important in paleontology as index fossils and for understanding evolutionary biology.

FAQ
Frequently Asked Questions
No. While they look superficially similar due to their two-part shells, brachiopods are a separate phylum (Brachiopoda) with a completely different internal anatomy and evolutionary history from bivalve molluscs (clams, mussels).
Yes, but they are far less common than in the geological past. A few hundred species exist today, primarily in cold or deep-sea environments, whereas tens of thousands of fossil species are known.
They are excellent 'index fossils' for dating rock layers because many species existed for specific, limited geological time periods. Their fossil record is also crucial for studying patterns of evolution and extinction.
In British English, it's typically /ˈbrækɪə(ʊ)pɒd/ (BRACK-ee-oh-pod). In American English, it's commonly /ˈbreɪkiəˌpɑːd/ (BRAY-kee-uh-pahd). The first syllable can vary between 'brack' and 'brayk'.
A marine invertebrate animal belonging to the phylum Brachiopoda, characterized by a lophophore for feeding and having a two-valved shell, often resembling a clam in appearance but with a different anatomical structure.
Brachiopod is usually technical/scientific (primarily paleontology, zoology, marine biology) in register.
Learning
Memory Aids
Mnemonic
Think: BRACHis (Greek for 'arm') + POD (Greek for 'foot') = 'arm-foot', referring to the lophophore, its coiled feeding structure that looks a bit like arms. 'The BRACHioPOD uses its arm-foot to eat.'
Conceptual Metaphor
Not applicable. The term is a literal scientific label.
