This changed after the mass extinction at the end . Most brachiopods tolerate only normal marine salinity, but a few species, such as the ligulides, can live in brackish salinities. One of the biggest differences between brachiopods and bivalves lies in their symmetry. Brachiopoda –– 1. They have been found living in a wide range of water depths from very shallow waters of rocky shorelines to ocean floor three and a half miles beneath the ocean surface. They live on the ocean bottom in a variety of places, including soft sediments, on rocks, reefs, or in rock crevices where some even anchor themselves with a muscular stalk called a pedicle. Living brachiopods also fall into this range. Image by "Daderot" (Wikimedia Commons; Creative Commons CC0 1. However, they are no more related to bivalves than people are to starfish!

How do they feed, move, and reproduce. Brachiopods first appeared in the Cambrian Period , and have one of the best fossil records of any invertebrate group. The larvae of articulate species settle in quickly and form dense populations in well-defined areas while the larvae of inarticulate species swim for up to a month and have wide ranges. Where Do Brachiopods Live? Today, brachiopods live in cold marine environments like polar seas and continental shelves and continental slopes. Do brachiopods live in water? Most brachiopods live in relatively shallow marine water, up to about 650 feet (200 m), but some species have been found at depths of more than a mile. Because many fossils species are found in shales, which form from deposits of mud and silt, we know that some brachiopod species thrived in muddy environments. 1 Brachiopod Classification –– 1. There are some 30,000 fossil brachiopod species known, but only around 385 are alive today. ac. They live inside a pair of shells, much like the more numerous bivalves.
