Brachiopods phylum.

Brachiopods (/ ˈ b r æ k i oʊ ˌ p ɒ d /), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection.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.Gigantoproductus. Gigantoproductus is a genus of extinct brachiopods in the order Productida and the family Monticuliferidae.

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.
