The chitinous ribbon bearing the teeth of mollusks; -- called also lingual ribbon, and tongue. See Odontophore.
ribbon-shaped membrane with transverse rows of many small hard teeth, attached to floor of the inner mouth of molluscs (except bivalves) and used in rasping food.
The ribbon of teeth possessed by most gastropods (and most other molluscan Classes). The Muricidae have a ribbon of numerous lateral rows of teeth. Each row has a central tooth flanked on either side by a lateral tooth. Teeth may bear smaller teeth called cusps. The shape and disposition of the teeth are of taxonomic importance.
A rough tongue or band of horny teeth used by snails and other molluscs to scrape algae or bore into shells.
a file-like extensible feeding structure found in most opisthobranchs, it bears numerous chitinous teeth.
ribbon of backward pointing teeth covering the tongue of most mollusks. The teeth are composed of a material similar to chitin.
(plural: radulae) A rasp-like structure in the mouth with numerous chitinous teeth used to scrape, pierce, tear, or cut off small pieces of food that are then directed into the digestive tract. In most mollusks, the radula is like a flexible file or a ribbon of teeth. Radulae are unique to mollusks; no other creatures have them. Bivalves and some gastropod species lack radulae; these absences are interpreted as evolutionary loss of the radula. Different species of mollusks often have differently shaped radulae, so examining the radulae can help identify species and resolve their relationships to each other. Some radulae, as in the cone snails, are modified into hypodermic darts to inject poison into the prey.
A narrow tongue-like organ in the mouth of mollusks with rows of teeth
A rasping organ in the mouth of mollusca, used to scrape up food.
a rasp-like organ or lingual ribbon armed with tooth-like processes.
an organ that bears many rows of teeth and is used for grazing on food
a ribbon of teeth used in feeding Three coelomic (body cavity) spaces
a toothed chitinous ribbon used
a rasping tongue like organ present in mollusks, used to graze and break up food.
a flexible tongue-like organ in some molluscs that consists of rows of horny teeth on the surface.
Row of rasping teeth on a tongue-like structure behind the mandibles of many molluscs induding cephalopods. They are made of chitin. Saddle Anterior-pointing folds in the septum where it meets the inner surface of the shell.
a chitinous band bearing numerous minute teeth that when drawn back and forth within the mouth of most molluscs, serves to break up food
RAD-yew-la A chitinous, tonguelike structure that mollusks use to eat. 519
n. A feeding organ of molluscs that contains teethlike structures for scraping food off surfaces and drawing food into the mouth.
The tooth-lined tongue of a giant squid.
rasp-like tongue with tiny teeth found in many mollusks
A tongue unique to molluscs. It is usually a strip or ribbon of flesh covered with tiny, hard teeth. The radula is often used like a file. The features of the radula matches the diet of its owner, e.g., to rasp off algae or drill through a shell. In some, the radula is modified into a piercing organ to inject venom.
the rasping tongue found in most molluscs (Phylum Mollusca, snails, bivalves, and cephalopods). Tongue-like structure covered with tiny teeth which is protruded from the mouth, and used to scrape food items back into the pharynx. Synapomorphy of Mollusca.
Radula is the scientific name for the toothed chitinous ribbon in the mouth of gastropods. They use it to graze and scrape diatoms and other microscopic algae off rock surfaces and other substrata.
