The data used in this paper was obtained from the comprehensive oceanographic survey during the First Chinese National Arctic Research Expedition in Chukchi Sea and Bering Sea in July and August 1999. The characteristics of ecological groups, species composition, horizontal and vertical distribution of Chaetognatha in both Chukchi Sea and Bering Sea are described and the relationships of Chaetognatha density and some other environmental factors are discussed.
