中文摘要：

在 2009 年 10 月 1 日，十六只海豚被在黄海的偶然的抓住从渔民获得，中国。因为海豚肤色是模糊的，词法参数被测量，并且 mitochondrial DNA 细胞色素 b (Cyt b ) 基因顺序被学习识别种类。词法特征与 Pantropical 一致看到的海豚， Stenella attenuata。而且，部分 mitochondrial DNA 细胞色素 b (Cyt b ) 基因顺序只要 328-bp 被提取 genomic 学习，从皮肤的 DNA，和六 haplotypes 在十六只海豚被检测。由比较在 GenBank (www.ncbi.nlm.nih.gov ) 可得到的相应序列，所有六 haplotypes 与 Pantropical 有最大的基因类似看到的海豚。鲸的(鲸鱼和海豚) 的八种现在在黄海被认出。就我们的知识而言，这是 Pantropical 的第一个记录从这个区域的看到的海豚。自从 1988，尽管有是被列出的这种，一把等级 II 国家钥匙保护了动物，很少被了解它用汉语的生物学流水。我们建议补救研究被承担保证适当管理。

英文摘要：

On October 1, 2009, sixteen dolphins were obtained from fishermen by incidental catching in the Yellow Sea, China. As the dolphins＇ skin color was ambiguous, morphological parameters were measured, and mitochondrial DNA cytochrome b （Cyt b） gene sequence was studied to identify the species. Morphological characteristics were consistent with Pantropical spotted dolphins, Stenella attenuata. Furthermore, a partial mitochondrial DNA eytoehrome b （Cyt b） gene sequence as long as 328-bp was studied by extracting genomic DNA from the skins, and six haplotypes were detected in the sixteen dolphins. By comparing homologous sequences available in GenBank （www.ncbi.nlm.nih.gov）, all the six haplotypes had maximal genetic similarity with Pantropical spotted dolphin. Eight species of cetacean （whales and dolphins） are now recognised in the Yellow Sea. To the best of our knowledge, this is the first record of Pantropical spotted dolphins from this region. Despite this species being listed as a Grade II National Key Protected Animal since 1988, little is known of its biology in Chinese waters. We recommend remedial research be undertaken to ensure appropriate management.
