What is a brachiopod
Brachiopods are marine animals belonging to their own phylum of the animal kingdom, Brachiopoda. Although relatively rare, modern brachiopods occupy a variety of seabed habitats ranging from the tropics to the cold waters of the Arctic and, especially, the Antarctic. Leptanena depressa (J Sowerby, 1824). BGS © UKRI.The brachiopods are a phylum of twin‐valved, often sessile, shellfish. They are marine, and filter feed using an organ called the lophophore, placing them in the clade Lophotrochozoa. Their diversity in the geological past – especially the Palaeozoic, following their Lower Cambrian origins – is far greater than today.
