Abstract

The two species of Chirocentrus, C. nudus and C. dorab, examined from
the Palk bay and Gulf of Mannar, appear to be diurnal predators preying
mostly on fishes, depending for predation perhaps on vision. They seem to ingest
the prey as a whole, swallowing its head first. When young, they feed mainly
oil the postlarvae and juveniles of Stolephorous and Sardinella and on Acetes,
but, as adult' they change over to adult sardines and other clupeoids. Though
both the species belong to the same trophic level, C. nudus seems to avoid competition
by feeding on relatively larger-sized prey, which they arc able to do
with the help of their larger mouth and stronger teeth.
