摘      要：Seamounts are vulnerable ecosystems in the deep sea and can be heavily impacted by human activities,such as bottom fishing and deep-sea *** species composition and distribution patterns of benthic fauna is key information for the designation of marine protected areas and environmental management *** contracts for cobalt-rich crust exploration have been granted to China,Japan and Korea in the Northwest Pacific Ocean by the International Seabed ***,our knowledge of benthic biodiversity in this area is extremely *** 2013–2020,eight Chinese Ocean Mineral Resources R&D Association(COMRA)cruises were conducted to investigate the benthic assemblages of nine seamounts in this *** this study,191 ophiuroids collected from seamounts in the Northwest Pacific were identified into 29 species in 11 *** and Euryalidae were the two most dominant families with 12 and 6 species,*** and Ophiopyrgidae were represented by two species each,while seven families were represented by only one *** species were widely distributed among 4–5 seamounts,and 17 species were found only at a single *** integrated regional taxonomic dataset of Ophiuroidea was generated and analyzed.A total of 23 and 14 species were obtained from the Magellan Seamount Chain(MSC)and the Marcus-Wake seamounts(MWS),respectively,with 8 species shared between the two seamount *** individual-based rarefaction curves did not reach an asymptote,suggesting that the sampling effort was inadequate for either the entire region or each single *** species distributed in a narrow depth range,and the species composition was different between water depths above and below 2000 *** results greatly improve the understanding of megafaunal biodiversity from seamounts in the Northwest Pacific Ocean,and highlight the necessity of further surveys to provide more robust information for environmental protection and manageme
