在加勒比海（哥伦比亚）的珊瑚礁中，通过测定水提取物产生的人红细胞中的延迟溶血（哇巴因预处理可抑制）和HPLC，在海葵属和Zoanthus属的zoanthid物种中检测到了海葵毒素（PTX）。珊瑚虫和菌落的毒素含量变化很大，与它们的生殖周期或共生藻类的数量无关。已经在甲壳类动物（Platypodiella sp.）生活在与海葵属群体密切相关的多毛类蠕虫中，以带状虫为食。海洋动物对这种毒素的抵抗力可能使它能够进入食物链。
In coral reefs of the Caribbean Sea (Colombia) palytoxin (PTX) has been detected in zoanthid species of the genera Palythoa and Zoanthus by assaying the delayed haemolysis in human erythrocytes produced by aqueous extracts, which is inhibited by ouabain pretreatment, and by HPLC. The toxin content of the polyps and colonies is highly variable and is not correlated with their reproductive cycle or with the amount of symbiotic algae. Sequestration of PTX has been observed in crustaceans (Platypodiella sp.) living in close association with Palythoa colonies and in polychaete worms (Hermodice carunculata) feeding on the zoanthids. Resistance of marine animals to the toxin may enable it to enter food chains.
