The non-indigenous sabellid polychaete (Grube, 1870) has spread along the Mediterranean coast in a short time period. Well-established populations were recorded for 9 marinas and 3 natural habitats along the southern Iberian Peninsula, including the first record of the species in Portugal. The highest abundances (>60 ind./m) were found in the Gulf of Cádiz (Atlantic coast of Spain). The ability to colonize artificial structures has also been tested experimentally; although the species showed high colonization rates, high water-flow rate and turbidity might adversely affect larval settlement. The tubes of hosted a very diverse epibiota, comprising 79 taxa, many of which are considered to be introduced or cryptogenic species. The ability of this polychaete to facilitate the spread of these species when attached to vessel hulls is discussed. Our results suggest that this species is in a phase of active colonization by successfully colonizing both natural and artificial habitats.

到地中海及其他地区：评估Branchiomma luctuosum（环节动物：Sabellidae）传播的综合方法

非本土萨贝利多毛类动物（Grube，1870）在短时间内沿着地中海沿岸传播。伊比利亚半岛南部的 9 个码头和 3 个自然栖息地都有稳定的种群记录，其中包括葡萄牙的首次记录。最高丰度（>60 ind./m）出现在加的斯湾（西班牙大西洋沿岸）。殖民人造建筑的能力也经过了实验测试。尽管该物种表现出较高的定植率，但高水流速率和浑浊度可能会对幼虫的沉降产生不利影响。管内寄生着非常多样化的表生物群，包括 79 个类群，其中许多被认为是引进物种或隐源物种。讨论了这种多毛类动物附着在船体上时促进这些物种传播的能力。我们的结果表明，该物种正处于积极殖民阶段，成功地殖民了自然和人工栖息地。
