Brachiopods are fascinating marine invertebrates often mistaken for clams, but they are entirely different organisms with a rich, 550-million-year history. Known commonly as "lamp shells," they were dominant in Paleozoic seas but are now relatively rare, often found in deep or cold waters.
Depending on species, they live between 3 to 30 years. 🦴 The Fossil Record What is a Brachiopod? (And Why You Should Care)
Unlike bivalves (clams), where shells are mirror images of each other, brachiopod shells are top/bottom oriented and distinct, but each individual valve is symmetrical down the middle.
