A study of the food and feeding habits of Megalaspis cordyla based on an examination of 1692 specimens revealed that it is a pelagic carnivorous feeder, subsisting mainly on Stolephorus spp.; Leiogiiathus spp., Gazza &p., Carangoides spp., fish juveniles, fish larvae, alima larvae of Squilla spp., Acetes spp., amphipods, Squilla spp., Lucifer spp., megalopa larvae of crab, prawn juveniles, copepods, euphausids, pteropods, Sepia spp., and Nereis spp. were the other food items recorded. The intensity of feeding decreased with advancement of maturity. Feeding was observed to be comparatively higher during night than by day.
