Exploratory cruises by the NOAA Ship Okeanos Explorer have resulted in a substantial contribution in our understanding of deep-sea echinoderm biodiversity, biology, and ecology in the North Atlantic. This includes the description and in situ feeding observations of two, new corallivorous goniasterid species, Evoplosoma nizinskiae n. sp. and Sibogaster bathyheuretor n. sp. Significant in situ observations include a synchronous feeding event including multiple goniasterid asteroids and a cidaroid urchin on a large demosponge, providing new data for understanding echinoderm feeding behavior, including agonistic behavior, in deep-sea settings and new, in situ feeding observations for 28 deep-sea species including the myxasterid Pythonaster atlantidis, the korethrasterid Remaster palmatus and the poorly understood hippasterine goniasterids, Gilbertaster caribaea and Sthenaster emmae.
美国国家海洋和大气管理局的“奥基诺斯探索者号”科考船进行的探索性航行，为我们了解北大西洋深海棘皮动物的生物多样性、生物学和生态学做出了重大贡献。这包括对两种新的食珊瑚角海星科物种的描述和现场摄食观察，即尼津斯基埃沃普洛索海星（Evoplosoma nizinskiae n. sp.）和深海热寻食西博格海星（Sibogaster bathyheuretor n. sp.）。重要的现场观察包括一次同步摄食事件，有多只角海星科小行星和一只刺冠海胆在一块大型海绵上摄食，为了解深海环境中棘皮动物的摄食行为（包括争斗行为）提供了新数据，还为28种深海物种提供了新的现场摄食观察，包括粘海星科的大西洋蟒蛇海星（Pythonaster atlantidis）、科雷斯海星科的掌状雷马斯海星（Remaster palmatus）以及了解甚少的希帕斯特角海星科物种加勒比吉尔伯塔海星（Gilbertaster caribaea）和艾玛斯氏强壮海星（Sthenaster emmae）。
