The invasive fan worm Branchiomma luctuosum (Grube, 1870), originally described from the Red Sea, is first reported here from the Albanian coasts, based on records held in Vlora Bay, a locality near to Valona harbour and Narta Lagoon. Possible pathways of arrival in the area are uncertain. However, species’ larval ecology and life-history traits suggest a secondary spreading through shipping. Social media data mining allowed the confirmation of its establishment in the area, with specimens showing high densities in shallow waters on artificial hard substrates and to backdate its arrival in the area since at least November 2016. Citizen science continues supporting marine biology in the Mediterranean area, especially in countries where proper field studies and research projects are still limited.

公民科学发现了阿尔巴尼亚的分支机构luctuosum luctuosum（Grube，1870年）（Annelida：Polychaeta：Sabellidae）的到来和建立。

根据瓦洛纳湾（Vallor港和纳尔塔泻湖附近）的记录，阿尔巴尼亚沿海地区首次报道了最初是从红海描述的侵袭性扇形蠕虫Branchiomma luctuosum（Grube，1870年）。到达该地区的可能途径尚不确定。然而，物种的幼虫生态学和生活史特征表明其通过运输而二次传播。社交媒体数据挖掘使人们得以确认其在该地区的建立，并且标本在人造硬质基底上的浅水区显示出高密度，并至少自2016年11月以来推迟了其进入该地区的时间。公民科学继续支持地中海地区的海洋生物学，尤其是在适当的实地研究和研究项目仍然有限的国家/地区。
