Answer:

A file-like rasping organ known as Radula is present in the mouth of Mollusca.

Explanation:

About Mollusca

  • It is the 2nd largest phylum after the phylum Arthropoda and comes under the category of invertebrates.
  • There are about 85000 species of Mollusca recognized now. It includes chiton, apple snail, slugs, clams, mussels, scallop, oyster, etc.

About Radula

  • It is a ribbon-shaped chitinous plate lying in the buccal cavity extending over the summit of the odontophore.
  • The posterior part of the radula is enclosed in a radular sac which represents the diverticulum from the floor of the buccal cavity.
  • The radula contains several rows of minute, recurved teeth. It continues to grow throughout life and replaces the old torn-off teeth. The teeth bear the sharp cutting edges which help in rasping the vegetable food.
