Despite being crucial for habitat provision and being able to inhabit most oceans and all depths, documentation of threats affecting antipatharian corals (known as black corals) is very limited. We provide the second report of sea anemones in the genus Nemanthus overgrowing antipatharian corals causing the death of either entire colonies or sections of them. Our observations are from shallow and mesophotic reefs at the epicentre of marine biodiversity in Indonesia. Other instances exist where Nemanthus sp., as well as various species of zoanthids, have been reported to be in ‘association’ with antipatharians from other regions, which suggests that this could be a widespread threat to antipatharians. It is urgent to investigate the causes and to document the long-term effects that the sea anemones and zoanthids are having, in order to understand how this phenomenon will affect antipatharian populations and the fauna they support.

尽管对于提供栖息地至关重要，并且能够在大多数海洋和所有深度栖息，但有关影响抗病性珊瑚（称为黑珊瑚）的威胁的文献非常有限。我们提供了Nemanthus属中海葵的第二份报告，该海葵中生长着大量的抗病性珊瑚，导致整个殖民地或部分殖民地死亡。我们的观察结果来自印度尼西亚海洋生物多样性震中的浅礁和中生礁。其他情况下，存在其中Nemanthus据报道，其他物种的拟南芥属以及其他种类的蠕虫类动物都与其他地区的反病者有“联系”，这表明这可能是对反病者的广泛威胁。迫切需要调查原因并记录海葵和拟南芥所具有的长期影响，以便了解这种现象将如何影响抗病种群和它们所支持的动物。
