The faunistic analysis of soft bottom benthic materials collected from the Aegean and Levantine coasts of Turkey in August 2016 and 2017 revealed a total of 7 sipuncula species and 975 individuals belonging to 6 genera. The maximum population density of sipunculans was found to be 1790 ind.m in the Aegean Sea and 730 ind.m in the Levantine Sea. Onchnesoma steenstrupii steenstrupii was the most dominant species, comprising 83.1-92.8% of the total number of specimens in the Aegean Sea and 87.2-96.2% of the total number of specimens in the Levantine Sea. Four major sipunculan assemblages were found in the regions, and the main environmental factors controlling these assemblages were depth, temperature, salinity, the sediment grain size, nutrients and total organic carbon. Different abiotic factors affected the distribution of different sipunculan species in the regions. The present study included two cryptogenic sipunculan species; Apionsoma (Apionsoma) misakianum and Aspidosiphon (Aspidosiphon) mexicanus.
2016 年和 2017 年 8 月，从土耳其爱琴海和地中海沿岸采集的软底底栖生物的动物地理分析显示，共有 7 种星虫和 975 个个体，分属于 6 个属。星虫的最大种群密度在爱琴海为 1790ind.m，在地中海为 730ind.m。Onchnesoma steenstrupii steenstrupii 是最占优势的物种，占爱琴海总标本数的 83.1-92.8%，占地中海总标本数的 87.2-96.2%。在这些地区发现了四个主要的星虫组合，控制这些组合的主要环境因素是深度、温度、盐度、沉积物粒度、营养物质和总有机碳。不同的非生物因素影响了不同星虫物种在这些地区的分布。本研究包括两个隐生星虫物种；Apionsoma (Apionsoma) misakianum 和 Aspidosiphon (Aspidosiphon) mexicanus。
