Brachiopod Official

They use a specialized organ called a lophophore , a coil-shaped tentacle structure, to trap food, rather than gills.

They are divided into two main groups: Inarticulates (no hinges, simple muscle systems) and Articulates (hinged with a complex system).

Here is a review of their significance, biology, and fossil record. 🌟 Key Takeaways brachiopod

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

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. They use a specialized organ called a lophophore

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 While decimated by the end-Permian

Depending on species, they live between 3 to 30 years. 🦴 The Fossil Record What is a Brachiopod? (And Why You Should Care)
