What is the function of a mollusk's radula?

Answer 1

Molluscs use a minutely toothed structure called radula for feeding.
Radula is called a rasping organ, present in most of gastropod molluscs.

The radula helps to graze upon microscopic filamentous algae from a surface and feed directly on plants. It is like a chitinous ribbon and is used for scrapping and cutting food before it enters the oesophagus.

The teeth on the membrane are called denticles and are constantly shed and regrown.

The radula is the only means of consuming food and plays a pivotal role in the survival of the animal.
