The odontophore is part of the feeding mechanism in molluscs. It is the cartilage which underlies and supports the radula, a ribbon of teeth. [1] The radula is found in every class of molluscs except for the bivalves. [2] The feeding apparatus can be extended from the mouth of the animal, and the radular ribbon can slide over the odontophore.
A typical radula comprises a number of bilaterally-symmetrical self-similar rows of teeth rooted in a radular membrane in the floor of their mouth cavity. Some species have teeth that bend with the membrane as it moves over the odontophore, whereas in other species, the teeth are firmly rooted in place, and the entire radular structure moves as one entity.
Gastropods (snails and slugs) as the largest taxonomic class of the mollusca are very diverse: the group includes carnivores, herbivores, scavengers, filter feeders, and even parasites. In particular, the radula is often highly adapted to the specific diet of the various group of gastropods.
The radula is odontophore, with teeth are arranged in transverse rows, ... Snails of species in the genus Pyrgulopsis occur in fresh water and in brackish water. [1]
4, The odontophore is broader than long, with a central minute, tricuspid tooth; the lateral teeth all similar, minutely 6-cuspid or pectiniform, on a curved edge, very closely set together and exceedingly numerous. 170—1—170+. 5. In generative organs, an amatorial organ present in the Burmese form is absent in the Indian. 6.

Unipectinate gills are found in a wide range of snails, including marine, freshwater, and even terrestrial forms. Examples include periwinkles, conches, and whelks. The water current is oblique, as it is in the turban shells, but many have developed a siphon formed from the rolled-up margin of the mantle. The siphon sucks in water to the mantle ...
A siphon is an anatomical structure which is part of the body of aquatic molluscs in three classes: Gastropoda, Bivalvia and Cephalopoda (members of these classes include saltwater and freshwater snails, clams, octopus, squid and relatives). Siphons in molluscs are tube-like structures in which water (or, more rarely, air) flows.
