Brachiopods (/ ˈ b r æ k i oʊ ˌ p ɒ d /), phylum Brachiopoda, are a group of lophotrochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve opod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major groups are recognized, articulate and.   Abstract—. The shell microstructure of two species of Bilobia, B. musca (Öpik, ) and B. alichovae Madison, (family Leptestiidae Öpik, ) from the Late Ordovician of Baltoscandia was studied. Possible primary layer, fibers, pseudopunctae, extropunctae, and the only known for strophomenides hollow punctae are described. Books. An illustration of two cells of a film strip. Video.

Brachiopods are virtually defenceless and their shell, enclosing the animal's organs, is their only protection. Most are permanently attached by a fleshy stalk (the pedicle) to a hard, sea-floor surface, such as a rock outcrop, boulder or some other shell, and are incapable of actively pursuing food. Brachiopods also normally have the ventral (lower) shell larger than the dorsal (upper) shell, whereas most bivalves have the two halves of their shell nearly equal. They are called Lamp Shells because the ventral valve in a number of mediterranean species resembles the shape of the oil lamps of ancient Greece and Rome. A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer created by an animal that lives in the shell is part of the body of the animal. Empty seashells are often found washed up on beaches by shells are empty because the animal has died and the soft parts have been eaten by another animal or have decomposed.
