摘要:
海水压强和水深超过2000m的里德堆和巴拉望海槽,可能是使活的鹦鹉螺Nautilus pompilius Linnaeus不能从菲律宾群岛向西分布的两大障碍。海流可能是影响鹦鹉螺类空壳分布最主要的限制因素。

ON THE GEOGRAPHICAL DISTRIBUTION OF RECENT NAUTILUS
Abstract:
The present study deals with the geographical distribution of living Nautilus and drift shells, the relationship between marine environmental factors and distribution and that between behavior and distribution. These results may be summarized as follows: 1. The pressure of sea water is probably the most important factor of the distribution limitation of living Nautilus. The Reed Bank and Palawan Trough, both are over 2,000 meters in depth, possibly constitute two great barriers that prevent the living Nautilus pompilius from distributing to the west of Philippine Islands. 2. The oceanic currents would be the most effective agency to move the drift shells of Nautilus. The distribution line of the drift shells of Nautilus pompilius from the east coast of Taiwan Province to the southern Japanese Islands of Pacific coast coincides with that of the current direction of Kuroshio.
