    Abstract
    Sex ratio in five species from south and southeast coast of India varied remarkably. Five species were selected for the present investigation. Range in the percentage of males was from 8 to 121 in @iUndinula vulgaris@@ (Dana), 16-425 in @iCentropages furcatus@@ (Dana), 3.5 to 47 in @iTemora turbinata@@ (Dana), 13 to 193 in @iTemora discaudata@@ Giesbrecht and 13 to 262 in @iCandacia bradyi@@ Scott. The ratio reached its maximum when the density of a species was low and when the numerical abundance was maximum the sex ratio was low. @iT. turbinata@@ was the only species which occurred in dense swarms during certain periods, completely absent in some collections and the only species which never showed male dominance. The four other species were present during all the cruises and in certain samples males dominated
