It was most abundant in September. Its arenaceous lorica is cylindro-conical in shape, （120-180）μm x （50-75）pm in size, agglutinated with mineral particles, and open at both ends. Two characters distinguish it from others： the unique lateral flattened posterior portion with a vertical aboral opening and wider oral diameter. It occurred in water with surface temperature of 14-27℃ and surface salinity of 3.9‰-29.8‰.展开更多
