The sequence variation analyses showed that there are 236 variable and 221 parsimony-informative in the aligned 605 nucleotide sites, in addition, the relative frequenencies of four nucleotides were not equal an this fact showed that the base compositions were biased. The results of phylogenetic analyses showed:(1) the phylogenetic relationships of the Cypraeidae taxa was basically in consistent with morphology-based ones;(2)Cypraeovulinae was monophyletic in all trees, whereas Nariinae and Cypraeinae were not;(3)the monophylies of Mauritia, Palmadusta, Erosaria, Monetaria, Staphylaea and Pustularia were strongly supported by molecular data;(4)Meyer's speculation that Chelycypraea came out from Luria were also supported.

结果表明：(1)宝贝科28种动物的分子系统树大部分与形态学分类一致；(2)在系统树上，疹贝与鼻贝亚科的其它分类群的距离相隔较远，提示它们之间有较远的亲缘关系，建议将疹贝属列入宝贝亚科；(3)卵宝贝亚科包括希达贝、脊焦贝、筛目贝、拟枣贝、焦掌贝以及呆足贝等共计15个属，它们在系统树上构成独立的一个大支系，构成单系群；(4)支持Meyer将龟甲贝从禄亚贝总属中分离出来的观点，但龟甲贝和林西那贝之间的系统发生关系及其分类地位还有待于进一步探讨。

Euphausia pacifica, Calanus sinicus, Themisto gracilipes, Crangon affinis and E. japonicus were the five most important prey species in the central and southern Yellow Sea. The total consumption of these preys by the fish community was over 2.33 million tons, accounting for 75.5% of the total food consumption.

太平洋磷虾、中华哲水蚤、细长脚虫戎、脊腹褐虾和鳀鱼同时是黄海中南部被摄食量最高的5种饵料生物，它们被摄食的生物量之和约为233万t，占总摄食量的75.5%。

Latimera was not significant, even smaller than that among populations with in groups. The results were similar to thoses obtained from morphology and molecular phylogenetics. All data strongly supported that H. tientsinensis and H. latimera was the same species. The difference of males'infraorbital crest between H.
