Abstract

Oratosquilla anomala is a carnivore, feeding on fishes, crustaceans, cephalopods, plant material, polychaetes, molluscans, and echinoderms in the order of importance. The index of preponderance and index of relative importance was found to be higher during monsoon season as compared to other seasons. Nature of food does not vary with the length groups.
