The abundance and higher taxonomic composition of epizooic metazoan meiobenthic communities associated with mussel and tubeworm aggregations of hydrocarbon seeps at Green Canyon, Atwater Valley, and Alaminos Canyon in depths between 1400 and 2800 m were studied and compared to the infaunal community of non-seep sediments nearby. Epizooic meiofaunal abundances of associated meiobenthos living in tubeworm bushes and mussel beds at seeps were extremely low (usually <100 ind. 10 cm(-2)), similar to epizooic meiofauna at deep-sea hydrothermal vents, and the communities were composed primarily of nematodes, copepods, ostracods, and halacarids. In contrast, epizooic meiobenthic abundance is lower than previous studies have reported for infauna from seep sediments. Interestingly, non-seep sediments contained higher abundances and higher taxonomic diversity than epizooic seep communities, although in situ primary production is restricted to seeps.
对位于格林峡谷、阿特沃特山谷和阿拉米诺斯峡谷，深度在1400至2800米之间的碳氢化合物渗漏处的贻贝和管虫聚集体相关的附生后生动物小型底栖生物群落的丰度和较高分类组成进行了研究，并与附近非渗漏沉积物的底内动物群落进行了比较。生活在渗漏处管虫丛和贻贝床中的相关小型底栖生物的附生小型动物丰度极低（通常<100个个体/10平方厘米），类似于深海热液喷口的附生小型动物，群落主要由线虫、桡足类、介形虫和海螨类组成。相比之下，附生小型底栖生物的丰度低于先前关于渗漏沉积物底内动物的研究报告。有趣的是，尽管原位初级生产仅限于渗漏处，但非渗漏沉积物的丰度更高，分类多样性也比附生渗漏群落更高。
