摘要
In this paper, the authors selected 9 samples from 8 species of Pseudoschwagerina in South China, counted the shell turns and measured axis specimen,thickness of the shell and axis of every circle. Using the parameters, the authors calculated their gravity,buoyancy in the sea water. With the movement of ocean current, the authors analyzed the influence of upwelling current on the 9 specimens. The results show that the small axis ratio of the Pseudoschwagerina, the stronger impact of upwelling current. Thus, the life style of the Pseudoschwagerina may change from the benthic to planktonic with the increase of hydrodynamic energy.
