Cephalopods are important members of deep-sea communities. However, the preference of many incirrate octopods for rocky substrate makes them largely unavailable with traditional sampling methods such as trawls. Therefore, much remains to be discovered about their diversity. This study focuses on the diversity and distribution of bathyal incirrate species in the western North Atlantic. We used observations from remotely operated vehicle (ROVs) videos, augmented by museum specimens and records from the Ocean Biogeographic Information System (OBIS), to compile a summary of the diversity of bathyal incirrates in the study area and their general distribution. In 22,861 approximately 5-min ROV video clips, we counted 2017 unique incirrate octopod individuals representing at least seven different species. Across observation types, the most common species we recorded were Bathypolypus bairdii Verrill, 1873, Graneledone verrucosa Verrill 1881, Muusoctopus spp., Scaeurgus unicirrhus Delle Chiaje in Ferussac & Orbigny, 1841, Pteroctopus tetracirrhus Delle Chiaje, 1830, and Tetracheledone spinicirrus Voss, 1955.

头足类动物是深海社区的重要成员。但是，许多不规则的八足动物对岩石底物的偏爱使得它们在传统的采样方法（例如拖网）中基本上不可用。因此，关于它们的多样性还有很多待发现。这项研究的重点是北大西洋西部海底不线形物种的多样性和分布。我们使用了来自遥控车（ROV）视频的观察结果，并通过博物馆标本和海洋生物地理信息系统（OBIS）的记录进行了补充，以汇总研究区域中的bath状线虫的多样性及其总体分布。在22,861个大约5分钟的ROV视频片段中，我们计算了代表至少七个不同物种的2017年独特的不规则八爪鱼个体。在各种观察类型中，Bathypolypus bairdii Verrill，1873，Graneledone verrucosa Verrill 1881，Muusoctopus spp。，Scaeurgus unicirrhus Delle Chiaje in Ferussac＆Orbigny，1841年，Pteroctopus tetracirrhus Delle Chiaje，1830年和Tetracheledone spinicirrus Voss，1873年
