Brachiopods phylum

Brachiopods are animals that live inside two shells (or valves) that show bilateral symmetry from side to side (i.e., if viewed from above or below). The top and bottom shells are not the same shape. To see this, look at the Side view in Figure 7.9: the valve on the left is the top and the valve on the right is the bottom.

That number has now dropped to 280 living species. The animal has two unequal valves which makes the brachiopod’s exoskeleton. They have a tiny heart with a poorly-developed circulatory system.The phylum Brachiopoda, or lamp-shells, consists of roughly 400 living and more than 12,000 fossil species of benthic, marine organisms. Both living and extinct brachiopods can be easily distinguished by their two valves, usually called dorsal and ventral. Molecular studies almost unanimously show Brachiopoda as a monophyletic group.

Phylum Brachiopoda. Brachiopods are sedentary marine invertebrates that possess a hard, mineralized shell consisting of two hinged halves (valves) that enclose the delicate soft body of the animal.
