This work investigates whether a submarine volcanic eruption off El Hierro (Canary Islands) in October 2011 influenced the metal contents of two deep water cephalopod species: Abraliopsis morisii and Pyroteuthis margaritifera. This was assessed by comparing metal contents in specimens collected off the island of El Hierro and in the neighbouring islands of La Palma and Tenerife during an experimental deep water fishing trip. The concentration of 20 heavy metals was analyzed in 180 specimens of A. morisii and P. margaritifera collected around the three islands to test for inter-island differences for each species and metal. While both species showed geographical differences in metal concentrations, the main finding was that A. morisii could be a bioindicator species for metals such as Li, Sr and Ca.
本研究调查了 2011 年 10 月埃尔埃希多（加那利群岛）附近的海底火山喷发是否影响了两种深海头足类动物的金属含量：Abraliopsis morisii 和 Pyroteuthis margaritifera。这是通过比较在埃尔埃希多岛和邻近的拉帕尔马岛和特内里费岛进行的深海捕鱼实验期间收集的标本中的金属含量来评估的。在这三个岛屿周围采集了 180 个 A. morisii 和 P. margaritifera 标本，分析了 20 种重金属的浓度，以测试每种金属在岛屿之间的差异。虽然这两个物种的金属浓度存在地理差异，但主要发现是 A. morisii 可能是 Li、Sr 和 Ca 等金属的生物指标物种。
