Brachiopod [WORKING]

They resemble ancient Roman oil lamps, especially the Terebratulida order.

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.

They were the most common shelled macroinvertebrates in the Paleozoic era. brachiopod

While decimated by the end-Permian mass extinction, they are not extinct, with ~400+ extant species. 🔬 Biology and Lifestyle

They are benthic (sea-floor dwellers) and sessile (permanently attached to the seafloor), generally filter-feeding. They resemble ancient Roman oil lamps, especially the

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.
