摘要在地中海东南部亚历山大港海岸潮间带首次记录到19种底栖多毛类。它们分别隶属于Syllidae(7种)、Hesionidae(3种)、Serpuidae(2种)和其他7科(各1种)。在这些物种中，Eunice miurai Carrera-Parra和Salazar-Vallejo 1998年似乎是地中海的新记录物种，而早些时候在地中海记录的4种外来物种是首次在埃及水域发现的：Opisthosyllis brunnea Langerhans 1879，Loimia Medusa Savigny 1822，Syllis Schulzi Hartmann-Schroder 1960，Phyllodoce long gifrons Ben-Eliahu 1972。新记录的物种在出现频率和数量丰度上表现出明显不同的模式。三角螺旋藻1758、舒尔兹螺旋藻、水母螺旋藻和棒状萨尔瓦多藻1863是亚历山大港沿岸污损样品中数量丰富的永久性物种。Bobretzky Bobretzky 1872在两个地点的沉积物中持续存在，压力较大的地点数量较多，而Protodrilus sp.另外两个地点全年都有人居住的沉积物，有时数量非常多。此外，早些时候发现的外来物种Brania arminii Langerhans 1881、Odontosyllis fulgurans Audouin&Milne-Edwards 1833和O.brunnea Langerhans 1879在亚历山大海岸经常被观察到。
Abstract Nineteen benthic polychaete species were recorded for the first time in the intertidal zone of the Alexandria coast, south-eastern Mediterranean Sea. They belong to Syllidae (7 species), Hesionidae (3 species), Serpulidae (2 species) and 7 other families (one species each). Of these species Eunice miurai Carrera-Parra & Salazar-Vallejo 1998 appears to be new to the Mediterranean Sea, while four of the alien species earlier recorded in the Mediterranean were found for the first time in Egyptian waters: Opisthosyllis brunnea Langerhans 1879, Loimia medusa Savigny 1822, Syllis schulzi Hartmann-Schroder 1960, Phyllodoce longifrons Ben-Eliahu 1972. The newly recorded species demonstrated markedly different patterns of frequency of occurrence and numerical abundance. Spirobranchus triqueter Linnaeus 1758, S. schulzi, L. medusa and Salvatoria clavata Claparede 1863 were permanent and abundant species in fouling samples along the Alexandria coast. Saccocirrus papillocercus Bobretzky 1872 persisted in the sediments at two sites, with a much higher count at the stressed one, while Protodrilus sp. inhabited sediments at two other sites throughout the year, sometimes in very high numbers. In addition, the alien species found earlier, Brania arminii Langerhans 1881, Odontosyllis fulgurans Audouin & Milne-Edwards 1833 and O. brunnea Langerhans 1879, were frequently observed along the Alexandria coast.
