Numerically, Limacina trochiformis was the main dominant specis in spring, attributed to its low temperature adaptation. Atlanta peroni was the dominant species in summer and Creseis acicula was the dominant species in autumn due to their adaptation to relatively high temperature. Agadina stimpsoniji was the dominant species in winter, adapted to low temperature.
