They are divided into two main groups: Inarticulates (no hinges, simple muscle systems) and Articulates (hinged with a complex system).
They use a specialized organ called a lophophore , a coil-shaped tentacle structure, to trap food, rather than gills.
Here is a review of their significance, biology, and fossil record. 🌟 Key Takeaways brachiopod
They resemble ancient Roman oil lamps, especially the Terebratulida order.
They were the most common shelled macroinvertebrates in the Paleozoic era. They are divided into two main groups: Inarticulates
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 are benthic (sea-floor dwellers) and sessile (permanently attached to the seafloor), generally filter-feeding. 🌟 Key Takeaways They resemble ancient Roman oil
While decimated by the end-Permian mass extinction, they are not extinct, with ~400+ extant species. 🔬 Biology and Lifestyle
