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.
