ABSTRACT
In this investigation Labeo dero and Glossogobius giuris were the material for study. Labeo dero is herbivorous and Glossogobius giuris is carnivorous. In Labeo dero, the food mainly comprised of algae, diatoms, plant material & zooplanktons. On the other hand in Glossogobius giuris, the food mainly consisted of animal nature such as crustacean, insects, larvae, small fishes & tadpoles. The mouth and buccopharyngeal region of the fishes under observation were modified according to the various kind of food. Hence in the present study special attention was laid down upon the modification of buccopharynx based upon the food and feeding habits.
Key words :Buccopharynx, Carnivorous, Herbivorous.
