| 根据2000～2004年共19个季度月对胶州湾进行系统的 5个全年度检测,对胶州湾肠鳃类动物的分布范围、出现率和栖息密度进行了分析和总结。结果表明,胶州湾的肠鳃类共分布有3科4属4种,即黄岛长吻虫 (Saccoglossus hwangtauensis)、三崎柱头虫(Balanoglossus misakensis)、多鳃孔舌形虫(Glossobalanus polybranchioporus)和青岛粗吻虫(Glandiceps qingdaoensis);前3种主要分布在潮间带,黄岛长吻虫在潮下带也有发现;青岛粗吻虫分布于湾内中西部潮下带,以湾顶部出现率高,栖息密度大。 肠鳃类的分布与底质有密切关系。 |

| Species and distribution of Enteropneusta from Jiaozhou Bay, Shandong |

| Abstract: |
| Based on the material collected from Jiaozhou Bay during 2000 to 2004, the paper reported the species and distribution of Enteropneusta. The results showed that four species belonging to 3 families and 4 genera have been found in Jiaozhou Bay, i.e. Saccoglossus hwangtauensis, Balanoglossus misakensis, Glossobalanus polybranchioporus and Glandiceps qingdaoensis. The first 3 species were found in the intertidal zones around the bay, in which Saccoglossus hwangtauensis was also found in the subtidal zone. Glandiceps qingdaoensis was found only in the subtidal zone of the bay, its highest abundance was found in the top of the bay. The distribution of enteropneustes relates strongly with the characteristic of the substratum. |
