The Mollusca are a LARGE phylum of invertebrate animals which includes Bivalves (which filter feed), Gastropods (which have radulae and even some with poison harpoons), Cephalopods, Squid and Octopus (Which have beaks and arms with suckers and hooks), Aplacophora (some of which are parasites). There are probably more ways in which mollusca have found to fee than has been mentioned here but his answer gives you an appreciation of the range of methods that have evolved.
In the process of feeding, it is noted that the gills of bivalves are important filtering the food that they eat and small food particles that stick to the mucous film of the gills is passed to the mouth of the clam. Half of the single shelled mollusks like snails also use radula to grind the algae from rocks. Most of the classes of phylum mollusks have radula except the bivalves. The radula teeth can be from 20 to more than 300 rows of teeth.

Bivalves are mollusks with two shells, such as a clam. A univalve is a mollusk with one shell, such as a snail.
Bivalves, univalves, and cephalopods are all types of mollusks. So are gastropods.

from ya mama UPDATE** mollusks filter feed. they take in water and then pumps out the waste water.
There is no such animal as a "univalve", however "bivalves" are filter feeders and filter seawater through their gills to pick up trace amounts of food.
They feed on mollusks, worms and other benthic organisms.
Bufflehead ducks feed on insects, crustaceans, and mollusks.
yes they are venomous relatives of sharks and they bottom feed on mollusks
