人们对深海矿藏的开发越来越感兴趣，特别是在富含多金属结核的中太平洋克拉里昂-克利珀顿区深海海底。为了有效地管理潜在的开发活动，需要彻底了解各种尺度上的生物多样性、群落结构、物种范围、连通性和生态系统功能。大型底栖动物在深海生态系统的运行中发挥着重要作用，是生物多样性的重要组成部分。虽然使用视频和静止图像的大型动物调查提供了对CCZ生物多样性的洞察，但需要收集动物样本来确认物种识别，以准确估计物种丰富度和物种范围，但很少进行动物收集。利用遥控潜水器，在CCZ西部3100-5100米深的三个环境特殊地区(APEI 1、APEI 4和APEI 7)的海山和深海平原上采集了55个底栖大型动物标本。利用形态和分子证据，共发现5门48种不同的形态类型，其中只有9种与已知种有关，39种可能是科学上的新种。这项工作突出表明，需要进行详细的分类学研究，不仅在CCZ内，而且在其他半深海、深海和半深海区域纳入遗传数据，作为可促进物种清单生成的代表性遗传参考文库。
There is a growing interest in the exploitation of deep-sea mineral deposits, particularly on the abyssal seafloor of the central Pacific Clarion-Clipperton Zone (CCZ), which is rich in polymetallic nodules. In order to effectively manage potential exploitation activities, a thorough understanding of the biodiversity, community structure, species ranges, connectivity, and ecosystem functions across a range of scales is needed. The benthic megafauna plays an important role in the functioning of deep-sea ecosystems and represents an important component of the biodiversity. While megafaunal surveys using video and still images have provided insight into CCZ biodiversity, the collection of faunal samples is needed to confirm species identifications to accurately estimate species richness and species ranges, but faunal collections are very rarely carried out. Using a Remotely Operated Vehicle, 55 specimens of benthic megafauna were collected from seamounts and abyssal plains in three Areas of Particular Environmental Interest (APEI 1, APEI 4, and APEI 7) at 3100–5100 m depth in the western CCZ. Using both morphological and molecular evidence, 48 different morphotypes belonging to five phyla were found, only nine referrable to known species, and 39 species potentially new to science. This work highlights the need for detailed taxonomic studies incorporating genetic data, not only within the CCZ, but in other bathyal, abyssal, and hadal regions, as representative genetic reference libraries that could facilitate the generation of species inventories.
